Abstract

The advancement of technology has provided various alternatives to address limitations in concrete construction. One effective method for enhancing the quality of concrete is by introducing additional materials, known as admixtures, during the concrete production phase. One such type of admixture that can significantly improve concrete quality is superplasticizer. The primary principle behind the use of superplasticizer is to create a repelling force between cement particles to prevent clumping, which can lead to the formation of air voids in the concrete. This, in turn, can reduce the strength or quality of the concrete. In this research, the focus will be on the use of concrete admixtures, specifically superplasticizer, to enhance concrete workability. One product of superplasticizer is Sika Viscocrete 3115 N, which will be used in this study. Superplasticizers like Sika Viscocrete 3115 N play a crucial role in improving the flow and workability of concrete mixes, making them easier to handle and place during construction. This leads to more efficient and high-quality concrete structures. The target compressive strengths are 30 MPa and 40 MPa with variations in the percentage of superplasticizer admixture usage at 0%, 0.25%, 0.5%, and 0.75%. The testing methods used to determine the workability value are the slump test and the slump flow test, while the compressive strength test is conducted using a compression testing machine at the Advanced Concrete Materials and Computational Mechanics Laboratory, Department of Civil Engineering, ITS. The study concludes that the addition of superplasticizer can enhance the workability of concrete but cannot optimally increase compressive strength. Additionally, different planned compressive strengths with the same percentage variation exhibit different trends. The addition of 0.25%-0.5% superplasticizer in both planned strengths still yields compressive strength above the planned levels, despite the decrease.

Abstract

Most bridge construction is dominated by steel bridges with various designs and structural types. The choice of steel as a material is due to its known strength, durability, and resistance to damage. However, if maintenance activities on steel bridges are lacking, there is a potential for damage or even failure of the structure. Structural failure can result in economic losses for the country, and more importantly, it can pose a threat to human safety. Therefore, there is a need for monitoring activities to assess the structural health. The development of monitoring activities in the last decade includes the Structural Health Monitoring System (SHMS). To address the challenges of SHMS, various methods are being researched. Non-Destructive Testing (NDT) methods are considered the best choice as an inspection tool, being perceived as easy, and effective in detecting and diagnosing various structural issues. Hence, in research, the detection of damage locations in steel bridge structures is carried out using the Mode Shape Curvature (MSC) method with the assistance of an accelerometer sensor. The MSC method contributes to SHM at level II, specifically in detecting the location of damage in the structure. It is observed that in the designed damage scenarios, the MSC index indicates a loss of stiffness with an increase in the MSC value at the damage location.

Abstract

Kegagalan pada konstruksi baja tipe circular hollow section (CHS) ini sering kali terjadi pada bagian sambungan. Hasil pengujian menunjukkan adanya tegangan yang tinggi pada bagian sambungan sehingga membuat  kegagalan sering terjadi pada area tersebut, dikarenakan sendi plastis akan terbentuk terlebih dahulu pada bagian sambungan. Beban dinamis yang bekerja secara terus menerus juga dapat memperbesar peluang terjadinya kegagalan sambungan. Oleh karena itu, harus dilakukan analisis mengenai kapasitas sambungan baja tipe circular hollow section (CHS) melalui kurva histeresis akibat dari adanya beban dinamis yang bekerja pada struktur. Dalam penelitian ini, telah dilakukan analisis numerik menggunakan program bantu ABAQUS untuk memvalidasi hasil uji eksperimental. Kapasitas ultimate sambungan, rasio daktilitas, dan mode kegagalan juga telah dievaluasi dan dibandingkan antara hasil analisis numerik dan hasil uji eksperimental.

Abstract

Sambungan struktur baja rangka momen khusus memiliki beberapa persyaratan pendetailan pada sambungannya. Pendetailan perlu dilakukan guna menjaga daktilitas struktur tetap tinggi. Daktilitas tinggi dapat dicapai dengan proses disipasi energi pada balok dengan kata lain sambungan harus tetap pada kondisi elastis saat balok mencapai kegagalan. Salah satu cara memastikan disipasi energi terjadi balok adalah dengan sistem sambungan reduced beam section (RBS). Studi ini memverifikasi model sambungan RBS pada sumbu lemah kolom baja dari benda uji WEAK-DB600-SW dari eksperimen Lee dkk.  dengan aplikasi ANSYS. Permodelan WEAK-DB600-SW menghasilkan sudut rotasi 4% tanpa mengalami kegagalan. Momen yang dicapai saat rotasi 4% sebesar 1178,60 kN-m, lebih besar daripada kapasitas 0,80 Mpb sebesar 1044,79 kN-m. Sambungan hasil analisis numerik layak digunakan pada rangka momen khusus sesuai dengan peraturan AISC. Hasil normalisasi momen puncak pada muka kolom (M/Mpb) model analitikal mencapai 1,09 dengan perbedaan terhadap eksperimen Lee dkk. sebesar 0,5%.

Abstract

The use of steel materials in building construction opens new opportunities for sustainable development, as steel exhibits corrosion resistance, durability, and reliability in terms of strength and ductility. Digital Image Correlation (DIC) is non-contact technique in which digital images of the surface of a test object are captured using high-resolution cameras.  This study conducted measurements of strain distribution on the specimen's surface using the DIC method throughout the entire tensile testing process. The study particularly focuses on examining changes in strain distribution during the melting phase and the local deformation phase leading to fracture. In this research, a comparison will be made between the load-displacement curves obtained from experimental laboratory testing and the results analyzed using the DIC method for SS400-grade steel material. Based on the results of the tensile test and DIC analysis that have been conducted, conclusions have been drawn in the research. The tensile test results of SS400 steel material with a thickness of 6 mm, 8 mm, 10 mm, and 12 mm meet the quality requirements in the tested specification standards, and the results of the force-displacement curve between the experimental test results and the DIC method obtained a minimum deviation with a value below 10%,. Therefore, it can be concluded that the DIC method exhibits a reasonably good level of accuracy, making it suitable for validating the results of experimental tests.

Abstract

Selama ini di dalam desain struktur Eccentrically Braced Frames (EBF), link selalu didesain secara menyatu dengan balok lantai sehingga menyebabkan terjadinya overstrength pada bagian tersebut. Selain itu, desain tersebut juga menjadikan perbaikan pasca gempa menjadi kurang efisien baik dalam segi waktu serta biaya. Selama satu dekade ini, mulai banyak penelitian yang memodelkan replaceable link dengan berbagai pengembangan untuk mendapatkan elemen yang daktail ketika menghadapi gempa, begitu juga dengan penelitian ini. Penelitian ini bertujuan untuk mengetahui perilaku link dengan berbagai macam material terhadap daktilitas, energi disipasi, deformasi dan rotasi, serta pola kegagalan pasca terjadi gempa. Pada penelitian ini dilakukan pengujian terhadap empat spesimen web bolted replaceable link dengan variasi material baja konvensional dan juga baja low yield pont (LYS). Analisa dilakukan dengan metode numerik yaitu dengan mengaplikasikan beban siklik bolak balik pada elemen link. Beban tersebut kemudian dikontrol trerhadap perpindahan di salah satu ujung link. Kemudian hasil pengujian dianalisa berdasarkan daktilitas, energi disipasi, deformasi, serta pola kegagalan. Hasil pemodelan menunjukkan link dengan tipe sambungan web bolted menghasilkan kurva dengan pinching effect yang disebabkan oleh sambungan baut. Selain itu, link LYS100 menunjukkan nilai rotasi yang besar dikarenakan material tersebut memiliki regangan ultimate yang lebih besar dibanding dengan baja konvensional. Dari pemodelan numerik didapatkan bahwa replaceable link dengan material LYS hasilnya sebanding dengan link dengan baja konvensional serta link tersebut mampu memenuhi persyaratan terkait daktilitas, kemampuan mendisipasi energi, serta besar rotasi yang dihasilkan.

Abstract

Steel-reinforced concrete (SRC) provides numerous advantages, such as enhanced energy dissipation, ductility, stiffness, and strength, particularly in seismic performance. Several studies on the effect of axial loads on columns found that axial loads have an insignificant influence on column capacity, though they influence long-term performance. Beam-column joint elements are among the critical components that determine the seismic behavior of a structure. Inaccurate design of these joints can lead to fatal structural damage, potentially causing structural collapse. This study aimed to perform a numerical analysis of various joint configurations under cyclic and axial loads to identify models with the best seismic performance that consisted of four models using different SRC length parameters. The research used nonlinear finite element methods with the ABAQUS software, which enables detailed simulations of joint behavior, including predictions of failure mechanisms that are difficult to observe in experimental testing. The results of the analysis showed that the CS-02 model demonstrated the best seismic performance. Axial load increased the capacity in all models, improved energy dissipation in the RC model, slightly reduced dissipation in CS models, and caused different rotational behavior across models.
