Abstract

Penelitian ini dibuat untuk mengatasi tantangan kompleks dalam desain dan konstruksi bangunan melalui pemanfaatan Coupled Steel Plate Shear Wall (CSPSW). Dalam era pembangunan yang semakin dinamis, sistem struktural CSPSW memiliki daya dukung dan kekakuan yang diharapkan dapat menahan beban dinamik. Pemilihan sistem ini sebagai fokus penelitian dilandaskan kemampuannya dalam menghadirkan solusi dengan menggabungkan dua portal Steel Plate Shear Wall (SPSW) dengan Coupling Beam (CB). Dengan memanfaatkan kekakuan dan daya dukung dalam satu sistem terpadu, CSPSW menawarkan potensi untuk mendesain bangunan baja yang lebih efisien dan tahan terhadap berbagai kondisi lingkungan yang kompleks.
Metodologi penelitian ini merangkum pendekatan eksperimental dan analisis numerik yang terintegrasi. Melalui eksperimen CSPSW yang dilakukan oleh Daniel & Larry (2017), pemahaman lebih mendalam tentang respons strutural dan perilaku sistem CSPSW diperoleh. Sementara itu, analisis numerik memungkinkan simulasi perilaku sistem dalam berbagai skenario beban dan lingkungan. Pemodelan elemen hingga digunakan untuk mengakomodasi variasi geometri dan karakteristik material, serta untuk menguji performa struktural dalam situasi dinamik yang memerlukan kemampuan daya dukung dan kekakuan yang optimal. Pendekatan kombinasi ini diharapkan memberikan wawasan komprehensif tentang perilaku dan respons CSPSW dalam situasi dunia nyata.
Hasil validasi eksperimental CSPSW Flex dengan model numerik menggunakan Abaqus dengan selisih 0,75%. Modifikasi panjang coupling beam (CB) dan variasi section berpengaruh pada besarnya nilai disipasi energi. Modifikasi panjang coupling beam juga berpengaruh pada besarnya nilai deformasi out of plane. Dari perbandingan nilai disipasi energi dan juga gaya geser yang didapatkan pada masing-masing model CSPSW modifikasi, dapat disimpulkan bahwa intermediate coupling beam lebih efektif dibandingkan dengan long coupling beam.

This research is conducted to address complex challenges in the design and construction of buildings by utilizing Coupled Steel Plate Shear Wall (CSPSW). In an increasingly dynamic era of construction, the CSPSW structural system is expected to provide the necessary support and rigidity to withstand dynamic loads. The choice of this system as the focus of the research is based on its ability to present solutions by combining two portal Steel Plate Shear Walls (SPSW) with a Coupling Beam (CB). By harnessing the rigidity and support in one integrated system, CSPSW offers the potential to design more efficient and environmentally resilient steel buildings.
The research methodology summarizes an integrated approach of experimental and numerical analysis. Through CSPSW experiments conducted by Daniel & Larry (2017), a deeper understanding of the structural response and behavior of the CSPSW system was obtained. Meanwhile, numerical analysis allows the simulation of the system's behavior in various load scenarios and environments. Finite element modeling is used to accommodate variations in geometry and material characteristics and to test structural performance in dynamic situations that require optimal support and rigidity. This combined approach is expected to provide comprehensive insights into the behavior and response of CSPSW in real-world situations.
The validation results of experimental CSPSW Flex with numerical modeling using Abaqus showed a difference of 0.75%. Modifications in the length of the coupling beam (CB) and variations in section significantly influenced the dissipated energy value. Changes in the length of the coupling beam also affected the magnitude of out-of-plane deformation. From the comparison of energy dissipation values and shear forces obtained in each modified CSPSW model, it can be concluded that an intermediate coupling beam is more effective compared to a long coupling beam.
