Abstract

Generally the concrete behavior can be observed by the experimental analysis. However, since the computer technology development has been increased rapidly, the computer simulations are also able to represent the detail behavior of concrete. This paper presents the modeling response of concrete material subjected to biaxial loading using finite element method software based. The plain concrete plates with dimensions 200mm x 200mm x 50mm and 150mm x 150mm x 50mm are analyzed using various combinations of biaxial loading. The results of the biaxial load combinations are covering the three non-linear regions of compression–compression, compression–tension, and tension–tension. The results of finite element analysis are also show good agreement to the experimental results that been taken from the previous study. The comparison results the difference between analytical and experimental study are less than 5%. Therefore, the concrete material model based on this finite element method software can be used to simulate the responses in the real condition.

Abstract

Precast concrete offers several advantages compared to conventional systems; precast concrete structure technology has become a strategy to enhance standardization, quality control, labor efficiency, and reduce environmental impact and construction pollution. The U-Shell precast beam is a reinforced concrete beam with a 'U' shape designed to enhance practicality and expedite the construction process as it does not require additional formwork and shoring during implementation. The U-Shell beam functions as a permanent formwork, and its design follows either monolithic or conventional methods. In multi-story buildings, using U-Shell beam can increase practical value, reduce costs, and improve time efficiency because they do not require additional formwork and scaffolding in the implementation application. This research involves the development of U-Shell precast beams, structure loading considering various loads, modeling using computer program to determine the structural reactions on each element, reinforcement design for the U-Shell beam structure, and analysis of the lifting and assembly of U-Shell precast beam. The building selected for reviewing U-Shell beams is the Building with a Special Moment Resisting Frame System. From the results of the analysis, the researcher drew several conclusions regarding the reinforcement design for the U-Shell beam under both conditions. In the condition before composite, the number of installed main reinforcements is 6 with a diameter of 13 mm, while in the condition after composite, the number increases to 8 with a diameter of 16 mm. Lifting reinforcement requires a diameter of 10 mm. The difference in reinforcement between before composite and after composite conditions is because before the composite the beam is still receiving self-load, whereas for the after composite condition the change in moment occurs. After all, the beam has received self-load and other loads. The development and analysis of an innovative precast concrete U-Sheel beam has complied with strength and serviceability.

Abstract

Penggunaan material baja dalam konstruksi bangunan menjadikan peluang baru menuju pembangunan berkelanjutan, karena material baja memiliki sifat tahan lama dan handal dalam kekuatan dan daktilitas. Digital Image Correlation (DIC) merupakan teknik non-kontak dimana gambar digital permukaan benda uji ditangkap menggunakan kamera resolusi tinggi. Dalam penelitian, dilakukan pengukuran distribusi regangan di permukaan spesimen dengan menggunakan metode-DIC selama seluruh proses pengujian tarik material dan terutama meneliti perubahan distribusi regangan selama fase meleleh serta tahap deformasi lokal hingga gagal. Kemudian, dilakukan perbandingan kurva load-displacement hasil pengujian eksperimental laboratorium dengan hasil analisis menggunakan metode metode-DIC terhadap material baja dengan mutu SS400. Berdasarkan hasil penelitian dari uji tarik dan analisis DIC yang telah dilakukan, maka diperoleh kesimpulan dalam penelitian. Hasil pengujian tarik material baja dengan mutu SS400 ketebalan 6 mm, 8 mm, 10 mm, dan 12 mm memenuhi persyaratan mutu pada standar spesifikasi yang diuji, serta hasil kurva force-displacement antara hasil pengujian eksperimental dan metode-DIC didapatkan penyimpangan minimum dengan nilai dibawah 10%, hal ini dapat disimpulkan bahwa metode-DIC memiliki tingkat keakurasian yang cukup baik, sehingga dapat digunakan untuk memvalidasi hasil pengujian eksperimental.

Abstract

Indonesia is located in one of the world's most seismically active regions, requiring high-rise buildings to be designed with adequate seismic resistance to control excessive lateral deformation and prevent structural instability caused by the P–Δ effect. This study evaluates the seismic performance of a multi-story building equipped with different Fluid Viscous Damper (FVD) configurations using Nonlinear Time History Analysis (NLTHA). Three structural models were investigated: a bare frame structure without dampers (Model A), a structure with uniformly distributed FVDs (Model B), and a structure with FVDs installed only at stories experiencing the largest inter-story drifts (Model C). Three scaled historical earthquake records—Imperial Valley, Loma Prieta, and Northridge—were employed according to the seismic requirements of SNI 1726:2019. The results demonstrate that Model A exceeded the allowable inter-story drift limits at several critical stories. Although Model B produced the greatest drift reduction, it significantly increased structural stiffness because of the extensive bracing system. In contrast, Model C effectively reduced inter-story drift to within the allowable limits while maintaining greater structural flexibility. These findings indicate that strategically placing FVDs at critical stories provides a more efficient seismic mitigation strategy than conventional uniform damper installation.
