Abstract

Abstrak. Salah satu persyaratan penting untuk konstruksi tahan gempa yang terkait dengan pengekangan adalah pemasangan tulangan pengekang dengan kait gempa 1350 pada sengkang. Dalam pelaksanaannya banyak pelaksana konstruksi menggunakan tulangan pengekang dengan kait 900 atau dengan konfigurasi dobel C (tidak sesuai standar). Berdasarkan beberapa hasil penelitian dan beberapa catatan dari kejadian gempa di Indonesia akhir-akhir ini, pemasangan tulangan pengekang yang tidak sesuai standar untuk kolom beton bertulang menghasilkan kinerja yang buruk sebagai struktur tahan gempa. Makalah ini memaparkan hasil eksperimen yang bertujuan mengembangkan elemen tambahan (pen-binder) untuk meningkatkan efektivitas pengekangan kolom beton dengan tulangan pengekang yang tidak sesuai standar. Efektivitas dari tambahan elemen untuk meningkatkan kinerja pengekangan pada beberapa konfigurasi tulangan pengekang yang tidak standar ini diuji dengan beban aksial dan lateral siklis. Benda uji berjumlah 5 buah kolom, dimensi penampang 260 mm x 260 mm dan tinggi 1500 mm. Variabel pengujian adalah jenis material pen-binder,level beban aksial dan sudut kait yang digunakan dalam tulangan pengekang. Hasil pengujian menunjukkan bahwa modifikasi terhadap tulangan pengekang tidak standar efektif mengekang inti beton, meningkatkan daktilitas dan kemampuan disipasi energikolom benda uji.Abstract. One of the important requirements for earthquake resistant buildings associated with confinement is the use of seismic hook (135-degree hook) in hoop. Therefore, in practice many construction workers use confining reinforcement 90-degree hook or with double C configuration (code non-compliance). Based on some research and some records of recent earthquakes in Indonesia, the use of the code non-compliance confining reinforcement for reinforced concrete columns can result in structures with poor seismic performance. This paper presents the results of experimental study with an objective to develop an additional element (pen-binder) expected to improve the effectiveness of concrete columns confined with non-compliance confining reinforcement. The effectiveness of  this additional element in improving the performance of some configuration of non-compliance confining reinforcement in columns under axial and lateral cyclic loading was investigated in this study.The specimens tested in the study were 5 column specimens, with 260 mm x 260 mm in cross section and 1500 mm in height. The test variables were types of pen-binder material, level of axial load, angle of hook applied. The test results indicate that confining reinforcement modification can be effective in confining the core concrete, improving ductility and dissipation energy of column specimens.

Abstract

Abstrak. Offshore Platform biasanya menggunakan struktur baja tubular sebagai komponen utama penyusunnya. Kerusakan dapat terjadi pada bagian joint tubular, salah satu cara untuk memperbaikinya adalah dengan sistem grouted joint. Sistem grouted joint ini dianggap efektif karena biayanya yang tidak terlalu mahal dibandingkan dengan cara yang lain serta tidak mengganggu kegiatan operasional platform karena pengerjaannya tidak menghasilkan api. Perumusan mengenai kapasitas dari tubular joint (tanpa grout dan dengan grout) sudah dirumuskan di dalam API RP 2A WSD (American Petroleum Institute Recommended Practice 2A Working Stress Design) 2007. Hasil perhitungan manual berdasarkan code API ini akan dicek dan dibandingkan serta dianalisis dengan hasil dari pemodelan elemen hingga. Dari hasil analisis diperoleh kenaikan kapasitas aksial tarik rata-rata yaitu 52,75% (min. -6% dan maks. 116%).Kenaikan kapasitas aksial tekan rata-rata yaitu 343,75% (min. 230% dan maks. 468%). Kenaikan kapasitas momen lentur searah bidang rata-rata yaitu 68,88% (min. 36% dan maks. 98%). Kenaikan kapasitas momen lentur keluar bidang rata-rata yaitu 220,50% (min. 71% dan maks.  577%). Sedangkan perbedaan hasil antara perhitungan manual berdasarkan API dan pemodelan elemen hingga memiliki perbedaan rata-rata sebesar 19% (min. 2% dan maks 42%).Abstract. Offshore platform are usually made of tubular steel as main component. Damage can occur in tubular joint, one way to restore the joint capacity is to apply grouted joint system. Grouted joint system is considered to be the most effective because the cost isn't too expensive compared to the other retrofitting and doesn't disturb the platform operations. Formulation of the capacity of the tubular joint already defined in API RP 2A WSD code (American Petroleum Institute Recommended Practice 2A Working Stress Design) 2007. Manual calculation results will be compared and analyzed with the results from finite element modeling. This research examined the amount of increase in tubular joint capacity of all the loadings. From the analysis shows that the increase in  axial tension capacity of the average is 52.75% (min. -6% and max. 116%). The increase the capacity of the average axial compression is 343.75% (min. 230% and max. 468%). The increase in in-plane bending moment capacity of the average is 68.88% (min. 36% and max. 98%). The increase in out-of-plane bending moment capacity of the average is 220.50% (min. 71% and max. 577%). While the difference in results between the manual calculations based on API and finite element modeling have an average difference of 19% (min. 2% and max 42%).

Abstract

AbtractExisting special bridges such as cable-stayed bridges which are complex in structure need to be evaluated against SNI 1725:2016 and SNI 2833:2016. Dr. Ir. Soekarno Bridge located in Manado, North Sulawesi, was used as case study. Analysis based on the performance of the bridge was conducted using the Nonlinear Static Pushover Analysis (NSPA) with three different load distributions and Nonlinear Time History Analysis (NLTHA). Due to the standard load of the bridge, the deflection was still below the allowable deflection. Girder has an overstress of 12% in the Service Ic combination. The cable also has overstress in Cable 7 between 0.4% and 6.2%. Lower segment pylon capacity was exceeded by earthquake load combination of 28%. Bridge performance shows that the bridge structure was at fully operational performance level and the element performance was at immediate occupancy level, each method shows different result in base shear and displacement. The result shows that re-evaluation for existing special bridges is required. The bridge performance has different base shear and displacement for each method. Nonlinear Time History Analysis is the better option for special bridge, Nonlinear Static Pushover Analysis method requires a further study to determine the ideal load distribution for special bridge because the load distribution is crucial to determine the result of pushover analysis. AbstrakJembatan khusus eksisting seperti jembatan cable stayed yang sangat kompleks perlu dievaluasi kinerjanya terhadap SNI 1725:2016 dan SNI 2833:2016. Studi kasus pada penelitian ini adalah Jembatan DR. Ir. Soekarno di Kota Manado, Sulawesi Utara. Dilakukan pula analisis berdasarkan kinerja dengan Nonlinear Static Pushover Analysis dengan tiga pola beban dan Nonlinear Time History Analysis. Akibat beban standar jembatan, lendutan yang terjadi masih dibawah lendutan ijin. Girder mengalami kelebihan tegangan sebesar 12% pada kombinasi beban Layan Ic. Kabel juga terjadi kelebihan tegangan pada Kabel 7 antara 0,4% sampai 6,2%. Kapasitas pylon segmen bawah terlampaui oleh kombinasi beban gempa sebesar 28%. Analisis kinerja struktur jembatan dengan dua metode didapatkan bahwa tingkat kinerja struktur adalah fully operational dan kinerja elemen adalah immediate occupancy, akan tetapi nilai base shear dan perpindahan berbeda untuk masing-masing metode. Hasil analisis menunjukkan bahwa jembatan khusus eksisting perlu di evaluasi ulang terhadap peraturan terbaru. Kinerja jembatan dengan dua analisis nonlinier yang dilakukan menunjukkan hasil yang berbeda, Nonlinear Time History Analysis tetap menjadi metode yang lebih baik untuk jembatan khusus sedangkan metode Nonlinier Static Pushover Analysis perlu penelitian lanjutan untuk menentukan distribusi beban pushover yang cocok digunakan untuk jembatan cable stayed, mengingat pola distribusi beban sangat menentukan hasil dari analisis pushover.

Abstract

AbstractThe type of offshore platform for oil and natural gas exploration that is widely used in Indonesia is steel jacket platform. Jacket type platforms are generally made of tubular steel. During the service life, jacket type platforms often suffer damage to the joints. One preferred repair method for platform structure elements is by grouting. In the API RP 2A WSD NORSOK N-004 regulations, the formulations of tubular joint capacity reinforced by grouting are specified. The formulations in the regulations are empirical equations that need to be examined experimentally in the lab or tested by finite element analysis method. In this study, testing using the finite element method is conducted. The discussion is limited to the type of tubular joint with double skin chord. By finite element analysis, the influence of grout thickness, grout strength, inner chord thickness, and outer chord thickness to capacity of tubular joints reinforced with grout is investigated. From the analysis, it was found that the thickness and strength of the grout do not have a significant effect on increasing tubular joint capacity. While the thickness of both the inner and outer chords have a significant effect on increasing the tubular joint capacity. By comparison, the results of finite element method analysis are quite close to the results based on API regulation and in general the API results are more conservative except for cases with out-of-plane bending load.AbstrakTipe anjungan lepas pantai untuk eksplorasi minyak dan gas alam yang banyak dipakai di lepas pantai Indonesia adalah tipe jaket baja. Anjungan tipe jaket umumnya dibuat dari baja tubular. Dalam masa layannya, anjungan tipe jaket sering mengalami kerusakan pada sambungan (joint). Salah satu metode perbaikan yang disukai untuk elemen struktur anjungan adalah dengan di-grout. Dalam peraturan API RP 2A WSD dan NORSOK N-004 telah diberikan formulasi perhitungan kapasitas sambungan tubular yang diperkuat grout. Formulasi pada peraturan-peraturan ini merupakan persamaan-persamaan empiris yang perlu diperiksa dengan eksperimental di lab atau diuji dengan analisis metode elemen hingga. Pada penelitian ini dilakukan pengujian dengan metode elemen hingga. Pembahasan dibatasi pada tipe sambungan tubular dengan batang utama (chord)  ganda. Dengan analisis elemen hingga akan dilihat pengaruh tebal grout, kuat grout, tebal chord dalam, dan tebal chord luar terhadap kapasitas sambungan tubular yang diperkuat di-grout. Dari hasil analisis diperoleh bahwa tebal dan kuat grout tidak memberikan pengaruh yang signifikan terhadap peningkatan kapasitas sambungan tubular (tubular joint). Sedangkan tebal chord dalam dan luar keduanya memberikan pengaruh yang signifikan terhadap peningkatan kapasitas sambungan tubular. Dari perbandingan diperoleh hasil-hasil analisis metode elemen hingga cukup mendekati  hasil-hasil berdasarkan peraturan API RP 2A WSD dan hasil persamaan API RP 2A WSD umumnya ada pada sisi konservatif kecuali pada kasus beban momen keluar bidang.

Abstract

The use of precast prestressed concrete girder bridges in Indonesia has been increasing rapidly due to their high quality, reliability, and faster construction on site. The girder components are typically designed for a specific bridge span and can be prefabricated. The Directorate General of Highways of the Ministry of PUPR (Bina Marga) has released a standard design for prestressed concrete girder bridges with a typical span of up to 40 m. This design is based on the bridge loading standard SNI 1725 2016, which determines the live traffic load through consensus due to limited data on actual traffic load measurement results. However, the Ministry of PUPR has been implementing actual traffic load measurements using weigh-in-motion (WIM) technology to directly measure the load of passing vehicles. In this study, a risk assessment of the failure risk of a standard Bina Marga bridge with a 40-m span prestressed concrete girder type was conducted based on B-WIM load measurements. The results of this assessment indicate that the standard Bina Marga bridge has a failure risk of 1.48 x 10-4, which is smaller than the acceptable risk of failure according to the AASHTO LRFD Bridge Design Specification as referenced in SNI 1725 2016.

Abstract

Abstrak Jembatan kabel pancang (cable stayed) Pasupati Bandung didesain berdasarkan peraturan perencanaan jembatan BMS-1992 dan beroperasi sejak tahun 2005. Mengikuti perkembangan data lalu lintas, data kegempaan dan perkembangan ilmu pengetahuan, peraturan perencanaan jembatan telah diperbarui beberapa kali sampai yang terbaru adalah SNI 1725:2016 tentang Pembebanan untuk Jembatan serta SNI 2833:2016 tentang Perencanaan Tahan Gempa untuk Jembatan. Peraturan terbaru menerapkan sejumlah peningkatan beban hidup rencana dan juga beban gempa rencana sehingga memerlukan kapasitas rencana lebih tinggi. Demi menjamin keselamatan dan fungsi jembatan, perlu dilakukan evaluasi menyeluruh untuk memastikan bahwa Jembatan Pasupati masih layak berdasarkan peraturan perencanaan dan pembebanan terbaru. Pada penelitian ini dilakukan analisis metode elemen hingga linier dan nonlinier sesuai dengan gambar as built jembatan mengikuti kriteria perencanaan dan pembebanan pada peraturan terbaru. Hasil analisis pembebanan vertikal menunjukkan kelebihan beban tidak begitu besar, sehingga masih dianggap memenuhi syarat. Hasil analisis linier memperhitungkan beban gempa dan beban vertikal menunjukkan kapasitas momen pada dasar pylon dan sambungan pylon dengan gelagar terlampaui. Untuk konfirmasi hasil analisis linier dengan kombinasi beban gempa yang melebihi kapasitas, dilakukan analisisi non-linier pushover. Hasil analisis pushover menunjukkan struktur jembatan berada pada level kinerja fully operational sesuai dengan yang disyaratkan. Hasil analisis menunjukkan tidak ada kerusakan struktural dan non-struktural yang berarti apabila terjadi beban gempa rencana dan struktur jembatan dianggap layak dan memenuhi peraturan-peraturan perencanaan terbaru. Abstract The Pasupati Cable Stayed Bridge in Bandung was designed based on the BMS-1992 bridge design code and has been in operation since 2005. Following the developments of traffic data, seismic data, and advancements in scientific knowledge, the bridge design codes have been updated several times, with the latest being SNI 1725:2016 on Loadings for Bridges and SNI 2833:2016 on Earthquake Resistant Design for Bridges. The latest regulations incorporate increased design live loads and earthquake loads, thus requiring a higher design capacity. To ensure the safety and functionality of the bridge, a comprehensive evaluation is necessary to confirm that the Pasupati Bridge still meets the latest design criteria and loading regulations. In this study, a finite element analysis using both linear and nonlinear methods was conducted based on the as-built bridge drawings, following the criteria set by the latest design codes. The results of the vertical loading analysis showed that the overload caused by increased load criteria was not significant and the bridge considerred safe. The linear analysis for combination of seismic and vertical loads showed that the moment capacity at the base of the pylons and pylon-to-girder connections was exceeded, revealing the possibility of plastic response. To further investigate the bridge's performance under design earthquake loads and assess its behavior beyond elastic limits, a nonlinear pushover analysis was conducted. This analysis demonstrated that the bridge structure achieved a fully operational performance level, as required. Importantly, the results indicated no significant structural damage when subjected to the design earthquake loads, thus confirming the bridge's compliance with the latest design code.

Abstract

Vehicle loading on bridges involves dynamic loads, exhibiting distinct behavior from static loads. Dynamic loads can lead to the phenomenon of dynamic load amplification, potentially increasing the effects of the static weight of vehicles on the bridge. Addressing these effects is crucial during bridge design to ensure safety. The Dynamic Amplification Factor (DAF) is employed in bridge design as a multiplier for the live load standard to account for these effects. This study aims to assess the DAF on two Bridge Weigh-in-Motion (B-WIM) systems in Indonesia: Pawiro Baru Bridge (ID-001) with an 18 m in span and Kaligawe Bridge (ID-004) with a 30 m in span. The methodology involves analyzing the bridge's structural response to passing vehicles using strain transducer sensors in the B-WIM system to calculate the DAF. Results indicate that the average DAF for light vehicles (GVW<25 ton) is 1.19 for ID-001 and 1.19 for ID-004. For heavy vehicles (GVW>=25 ton), it's 1.10 for ID-001 and 1.09 for ID-004. The analysis reveals a consistent correlation between DAF and GVW, with heavier vehicles yielding lower DAF values. This research suggests to a proposed DAF model as a function of GVW, which proved to be more efficient and accurate based on actual measurements. The model presents the potential to enhance the efficiency of bridge design. It generally yields lower DAF values compared to those stated in SNI 1725:2016, aiming to align design standards more closely with the actual dynamic behaviour of typical bridge types under varying vehicle loads. Keywords: bridge, dynamic amplification factor (DAF), Bridge Weigh-in-Motion (B-WIM), bridge design, gross vehicle weight (GVW)
