Abstract

This study analyzes the nonlinear performance of Special Concentrically Braced Steel Frames (SCBF) in high-rise buildings exceeding the height limits stipulated in SNI 1726 (48 meters). Three case studies were selected, which are steel buildings with 48 (for benchmarking), 64, and 80-meter heights. Motivated by the urban demand for space efficiency and the crucial need for seismic resistance in steel structures, this study aims to evaluate the ductility and plastic hinge behavior of SCBF in multi-storey steel buildings. The primary objectives are to analyze SCBF structural performance, compare ductility parameters ) based on design and first yield results, and determine forces and deformations in braces during Design Basis Earthquake (DBE) and Maximum Considered Earthquake (MCE) events. The methodology involves nonlinear pushover analysis using MIDAS GEN 2024 software, including plastic hinge and fiber element modeling. The results indicate that SCBF performance in 48 and 64 m building heights experienced plastic hinge failure in the braces during MCE, yet met DBE limitations. Only the 20-story building satisfied MCE limits. Comparisons of  and  values show consistency with the design plan but are lower at first yield compared to SNI 1726.

Abstract

Indonesia is one of the regions traversed by the ring of fire, where this route shows high earthquake intensity and results in building damage, leading to fatalities. Efforts are being made to reduce the impact of earthquake through the implementation of base isolation system. One of the materials forming the base isolation system is natural rubber. In this study, natural rubber will be replaced with ebonite rubber to determine its specifications and whether it is effective when used as the base material for the base isolation system. The materials mixed to form ebonite rubber include natural rubber (SIR 20), ZnO, Stearic Acid, Sulfur, CBS, TMTD, Carbon N330, Minarex, Antilux, Ionol, TMQ, Antioxidant (6-PPD), and Aktiplast. This formulation will create ebonite rubber, which will then undergo mechanical property testing, including hardness, tensile strength, elongation at break, and volume change, to determine the capability of ebonite rubber as a substitute for natural rubber. It was found that ebonite rubber has results of 88 shore A hardness, 14.6 Mpa tensile strength, 70% elongation at break, and 91.08% compression set. From the research results, it was found that ebonite rubber has a high hardness value, making it effective for bearing vertical loads. Abstrak Indonesia merupakan salah satu kawasan yang dilewati oleh jalur ring of fire dimana jalur tersebut menunjukkan intensitas gempa yang tinggi dan berdampak pada kerusakan gedung hingga menimbulkan korban jiwa. Upaya untuk mengurangi dampak gempa bumi yaitu dengan menerapkan  penggunaan sistem isolasi dasar pada bangunan. Salah satu bahan pembentuk sistem isolasi dasar adalah karet alamada penelitian ini karet alam akan ditukar dengan karet ebonit dengan tujuan untuk mengetahui efektivitas karet ebonit bila digunakan sebagai bahan dasar sistem isolasi dasar. Formulasi karet ebonit yang digunakan merupakan hasil pengembangan dari formulasi karet alam yang sudah diteliti sebelumnya. Adapun bahan yang dicampurkan sebagai pembentuk karet ebonit yaitu karet alam (SIR 20), ZnO, Stearic Acid, Sulfur, CBS, TMTD, Carbon N330, Minarex, Antilux, Ionol, TMQ, Antioxidant (6-PPD), dan Aktiplast. Formulasi tersebut akan membentuk karet ebonit dan kemudian dilakukan pengujian sifat mekanik yaitu kekerasan, kuat tarik, perpanjangan putus, dan perubahan volume untuk mengetahui kemampuan karet ebonit sebagai pengganti bahan dasar karet alam. Didapati bahwa karet ebonit memiliki hasil pengujian yaitu kekerasan 88 shore A, kuat tarik 14,6 Mpa, perpanjangan putus 70%, dan perubahan volume 91,08%. Dari hasil penelitian didapatkan bahwa karet ebonit memiliki nilai kekerasan dan kuat tarik yang baik, serta dapat menahan perpanjangan atau regangan sebelum putus hingga 70% sehingga dapat tarik kesimpulan bahwa karet ebonit efektif bila dijadikan bahan dasar dalam sistem isolasi dasar.

Abstract

Concrete is the primary choice for construction projects, including its use in aggressive environments such as coastal areas. The high sulfate content in these environments poses a threat to the durability and compressive strength of concrete. The impact of sulfate attack on concrete can result in degradation and a decrease in concrete quality. Several methods have been used to maintain the durability of concrete, such as applying coatings to the surface of the concrete or using pozzolanic materials in the concrete mixture. In this study, Fly Ash was used as a pozzolanic material to reduce the impact of sulfate attack on concrete. The experiment involved adding Fly Ash to the concrete mixture in proportions of 0%, 10%, 20%, 30%, 40%, and 50% by weight of cement. Three test specimens were made for each variation in diameter and height of 10 cm and 20 cm, respectively. The durability test of the concrete used a magnesium sulfate (MgSO4) solution with a dry-wet cycle method according to SNI 3407-2008, which was conducted after curing in water for 28 days. The results of the test showed that adding Fly Ash to the concrete mixture has been proven to reduce damage and minimize the degradation of concrete quality due to sulfate attack compared to normal concrete without the use of Fly Ash. The use of Fly Ash also increased the compressive strength of all test specimens compared to normal concrete without Fly Ash.

Abstract

Abstrak Seringnya terjadi gempa bumi di Indonesia menuntut perencana struktur untuk menyediakan sistem pemikul beban lateral pada bangunan, tidak terlepas pada struktur bangunan baja. Di antara sistem-sistem struktur yang tersedia, Sistem Rangka Pemikul Momen Khusus (SRPMK) banyak diterapkan dikarenakan daktilitasnya yang tinggi dan disukai arsitek karena desainnya yang multifungsi. Penelitian ini mengevaluasi kinerja seismik dari SRPMK pada gedung baja 5 lantai dengan fungsi apartemen, dirancang sesuai SNI 1726:2019, SNI 1729:2020, SNI 7860:2020 dan SNI 7972:2020. Kinerja struktur diperiksa terhadap dua level bahaya gempa—Desain Basis Earthquake (DBE) dan Maximum Considered Earthquake (MCE)—seperti yang dispesifikasikan oleh ASCE 41-17, menggunakan analisis pushover dengan dua pendekatan pemodelan sendi plastis. Model 1 menggunakan sendi plastis dengan tipe deformation-controlled untuk perilaku lentur balok dan perilaku aksial-lentur kolom. Untuk Model 2, sendi plastis pada kolom dirubah menjadi tipe force-controlled didasarkan telah terpenuhinya kriteria perancangan strong-column-weak-beam saat mendesain ukuran penampang. Dua metode evaluasi kinerja struktur yaitu Capacity Spectrum Method (CSM) dan Displacement Coefficient Method (DCM) digunakan untuk memeriksa kinerja struktur. Melalui dua metode tersebut, hasil penelitian menunjukkan pemodelan sendi plastis pada Model 1 menghasilkan evaluasi kinerja struktur yang lebih baik dibandingkan Model 2. Kata-kata Kunci: Analisis pushover, deformation-controlled, evaluasi kinerja, force-controlled, SRPMK. Abstract Indonesia's frequent seismic activity necessitates that structural engineers incorporate effective lateral load-resisting systems in building designs, particularly for steel structures. Among the available systems, the Special Moment Resisting Frame (SMRF) is widely adopted due to its ductility and is favored by architects for its design versatility. This study evaluates the seismic performance of an SMRF system in a five-story steel apartment building, designed in accordance with SNI 1726:2019, SNI 1729:2020, SNI 7860:2020, and SNI 7972:2020. The structural performance is assessed against two seismic hazard levels—Desain Basis Earthquake (DBE) and Maximum Considered Earthquake (MCE)—as specified in ASCE 41-17, using pushover analysis with two different plastic hinge modeling approaches. Model 1 employs deformation-controlled plastic hinges for both beam flexural behavior and column axial-flexural behavior, while Model 2 modifies the column hinges to be force-controlled, based on the fulfillment of the strong-column-weak-beam design criterion. Two methods of performance evaluation, the Capacity Spectrum Method (CSM) and the Displacement Coefficient Method (DCM), are used to assess the structural performance. Through these two methods, the results show that the plastic hinge modeling in Model 1 yields better structural performance evaluation compared to Model 2. Keywords: Deformation-controlled, force-controlled, SMRF, performance evaluation, pushover analysis.

Abstract

The aluminium steel structures have relatively long term durability, high strength-to-weight ratio, and corrosion resistance. Investigations on the strength and performance of aluminium structures, both as a structural beam and column, can be found in various existing literature. However, studies that investigate the behaviour and strength of aluminium beams with a web hole remain scarce to date, even though the hole can accommodate building utility lines going through a structural element. This research aims to study the behaviour and strength of perforated aluminium beams using finite element modelling to simulate failure due to a three-point loading scheme. The finite element (FE) model in this study employed two approaches: full-section modelling and half-section modelling, which were then compared to the referred experimental test results. In total, 14 test specimens were built in the FE models, where the failure modes as well as the moment versus curvature curves obtained from the FE models, were quite similar to the test results. Furthermore, failure loads obtained from the test and FE models were very close, with the mean of test-to-FE loads was 0.97 and the coefficient of variation (COV) of 0.038 at maximum. It demonstrates that the numerical model developed in this study is valuable for further parametric study of the aluminium perforated beam, which fails under a three-point loading scheme.

Abstract

Project management is the most important thing in a series of stages of implementing a project. First stage is analyzing and observing, second: initial preparation, third: map of planning, fourth: implementation, and the last one is evaluation towards the whole process. The cost overruns can be caused from the desain changes which causes the construction delay and exceeding the deadline, as took place in the flyover construction of Grand Wisata Bekasi. This leads to the requirement of the review of the factors which caused the delay in the execution and during the construction stage. According to the observation during an internship, it was found that the communication is the main factor which had caused the delay. Poor communication on a project results in losses for the project owner due to non-fulfillment of implementation targets. From the contractor's side, the losses obtained are cost overruns. In addition, communities around the project also experience losses in the form of prolonged air and noise pollution due to delayed construction work. Abstrak Manajemen proyek adalah  suatu hal terpenting dalam rangkaian tahapan melaksanakan suatu proyek. Tahap pertama: menganalisis dan mempelajari, tahap kedua: persiapan awal, tahap ketiga: pemetaan rencana, tahap keempat: pelaksanaan, dan tahap yang terakhir: evaluasi kerja dari seluruh proses pelaksanaan. Anggaran yang membengkak diakibatkan oleh perubahan desain perencanaan yang selanjutnya mengakibatkan keterlambatan waktu atau melewati deadline, seperti yang terjadi pada proyek pembangunan flyover Grand Wisata Bekasi. Hal ini menjadikan perlunya  ditinjau kembali akan faktor apa saja yang menjadi menjadi hambatan dalam pelaksanaan proyek dan pada saat pelaksanaan pembangunan. Berdasarkan hasil pengamatan selama kegiatan magang pada proyek, ditemukan faktor komunikasi sebagai faktor utama yang menyebabkan terjadinya keterlambatan. Padahal komunikasi yang efektif dapat mempercepat/menyelesaikan masalah/hambatan yang ada di proyek. Komunikasi yang buruk pada proyek mengakibatkan kerugian pada pemilik proyek karena tidak dipenuhinya target pelaksanaan. Dari sisi kontraktor, kerugian yang diperoleh yaitu pembengkakan biaya. Sebagai tambahan, masyarakat sekitar proyek juga mengalami kerugian berupa polusi udara dan kebisingan yang berkepanjangan akibat pekerjaan konstruksi yang molor.

Abstract

This research aims to analyze the factors contributing to material procurement delays in the construction project of Station X. Delays in material procurement can have serious implications for project progress and budgets. Therefore, a profound understanding of the factors influencing these delays is crucial for enhancing construction project efficiency. This study employs factor analysis to evaluate historical data on material procurement in previous projects. The analyzed data include sudden order changes, material re-deliveries, and shifts in material requirements. The results of the factor analysis indicate that the most dominant factor influencing the risk of delays is "sudden order changes," signifying that effective change management is key to mitigating delays. The findings of this research have significant implications for construction practitioners and project managers in identifying and addressing material procurement delay risks. Recommended preventive measures include the development of sound procedures for managing order changes, improved communication, and more vigilant oversight of changes within projects. This research can serve as a vital foundation for construction project stakeholders to optimize material procurement management and reduce delay risks in similar projects in the future. Abstrak Penelitian ini bertujuan untuk menganalisis faktor-faktor yang berkontribusi terhadap keterlambatan pengadaan material pada proyek pembangunan Stasiun X. Keterlambatan dalam pengadaan material dapat memiliki dampak serius pada kemajuan proyek dan anggaran. Oleh karena itu, pemahaman mendalam tentang faktor-faktor yang mempengaruhi keterlambatan ini menjadi penting untuk meningkatkan efisiensi proyek konstruksi. Penelitian ini menggunakan metode analisis faktor untuk mengevaluasi data historis pengadaan material pada proyek-proyek sebelumnya. Data yang dianalisis mencakup perubahan pesanan, pengiriman ulang material, dan perubahan kebutuhan material. Hasil analisis faktor menunjukkan bahwa faktor yang paling dominan dalam mempengaruhi risiko keterlambatan adalah "perubahan pesanan yang tiba-tiba," yang mengindikasikan bahwa manajemen perubahan yang efektif adalah kunci untuk mengurangi risiko keterlambatan. Temuan penelitian ini memiliki implikasi penting bagi praktisi konstruksi dan manajer proyek dalam mengidentifikasi dan mengatasi risiko keterlambatan pengadaan material. Langkah-langkah pencegahan yang dianjurkan termasuk pengembangan prosedur yang baik untuk mengelola perubahan pesanan, peningkatan komunikasi, dan pengawasan yang lebih teliti terhadap perubahan dalam proyek. Penelitian ini dapat menjadi landasan penting bagi pemangku kepentingan proyek konstruksi untuk mengoptimalkan manajemen pengadaan material dan mengurangi risiko keterlambatan dalam proyek-proyek serupa di masa depan.

Abstract

This study utilizes pushover analysis to evaluate the performance of Intermediate Moment Resisting Frame System (IMRFS) used as the lateral force resisting system on the five stories building. Two structural models were analysed with differences on plastic hinge allocations and the controlling behaviour. On Model 1, plastic hinges were assigned to the designated beam and columns with deformation-controlled behaviour, while on Model 2, the plastic hinges on the columns were changed to force-controlled. Building modelling was in 3-dimension using ETABS v.20.0.0. Evaluations of the structural performance used two methods. Based on the structural performance evaluation using the Capacity Spectrum Method (CSM) and the Displacement Coefficient Method (DCM), the performance level of Model 1 is IO–LS in the X direction and > CP in the Y direction. Meanwhile, the performance level achieved by Model 2 is > CP in both the X and Y directions. In addition to the performance level evaluation, verification was also conducted on the values of the response modification factor (R), overstrength factor (Ω₀), and deflection amplification factor (Cd) obtained from the pushover analysis. The R values for both models are approximately 3, which is lower than the R value specified for SRPMM in SNI 1726:2019. The Ω₀ values for Models 1 and Model 2 are approximately 1.5 and 2.4, respectively. The Cd values for Models 1 and Model 2 range from 4.3 to 4.8 and from 5.5 to 5.8, respectively, for both the X and Y directions.

Abstract

The study was conducted on a six story plus an additional roof level of Special Concentrically Braced Frame (SCBF) steel structure. The lateral force resisting system consists of inverted-V bracing arranged as single-bay frames along each building perimeter. Variable of this study is the location of plastic hinges. In model 1, deformation controlled plastic hinges are assigned to the bracing, while force controlled plastic hinges are assigned to the columns and beams. In model 2, deformation controlled plastic hinges are assigned to columns, beams, and bracing. Structural evaluation was performed using pushover analysis by ETABS. The results show that hinge location variations have minimal influence on the performance point and ductility parameters (R, Ω0, dan Cd). The average differences in base shear dan displacement at the performance point between model 1 dan model 2 are 0.51% and 0.56% respectively. The differences in ductility parameters for model 1 and model 2 are 1%, 0%, 1.4% in the x direction and 1%, 0%, 1% in the y direction for R, Ω0, dan Cd respectively. However, it significantly affects the plastic hinge mechanism and performance level. The first component to exceed >CP level in model 2 is the bracing, whereas in model 1 it is the beams. The performance targets for model 2 at the MCE hazard level is LS for both directions but the performance targets for model 1 at the MCE hazard level are LS in the x direction and CP in the y direction. Overall, model 1 exhibits poorer structural performance level. Abstrak Penelitian dilakukan pada struktur rangka baja terbreis konsentris khusus (RBKK), 6 lantai ditambah atap. Struktur penahan beban lateral berupa rangka baja dengan breis tipe V-terbalik (inverted-V) yang terdiri dari 1 bentang frame terletak di masing-masing perimeter bangunan. Variasi penelitian pada lokasi sendi plastis yaitu untuk model 1 lokasi sendi plastis deformation controlled ada di breis sedangkan force controlled ada di kolom dan balok sedangkan untuk model 2 lokasi sendi plastis deformation controlled ada di ketiga komponen struktur (kolom, balok, dan breis). Evaluasi struktur dilakukan menggunakan analisis pushover dengan bantuan program ETABS. Hasil penelitian menunjukan bahwa dengan variasi lokasi sendi plastis tidak memberikan banyak pengaruh terhadap performance point maupun nilai parameter daktilitas struktur (R, Ω0, dan Cd). Perbedaan rata-rata gaya geser dan deformasi pada performance point untuk model 1 dan model 2 berturut-turut adalah 0,51% dan 0,56%, sedangkan perbedaan nilai parameter daktilitas struktur antara model 1 dan model 2 untuk R, Ω0, dan Cd adalah 1%, 0%, 1,4% untuk arah x dan 1%, 0%, 1% untuk arah y. Namun, variasi pemodelan berpengaruh terhadap mekanisme sendi plastis dan target kinerja struktur. Komponen yang lebih dulu mencapai level >CP pada model 2 adalah breis sedangkan pada model 1 adalah balok. Target kinerja struktur di model 2 pada level gempa MCE adalah LS untuk arah x dan y. Target kinerja struktur di model 1 pada level gempa MCE adalah LS untuk arah x dan CP untuk arah y. Model 1 memberikan hasil kinerja yang lebih buruk.
