Abstract

Kinerja struktur baja modular bertingkat tinggi sangat dipengaruhi oleh mekanisme sambungan antar – modul (inter-module connections). Penggunaan sambungan dengan pendekatan model pegas translasi untuk mentransfer beban antar – modul diusulkan. Menggunakan komponen batang baja berulir (rod) dan shear key yang berfungsi mengunci pergerakan antar kolom. Tujuan dari penelitian ini adalah untuk mengetahui kapasitas maksimum tarik dan geser, distribusi tegangan, serta mode kegagalan pada sambungan modular antar – modul.
Metodologi yang digunakan pada penelitian ini adalah analisis numerik FEM dengan menerapkan beban monotonik. Validasi model menggunakan penelitian terdahulu, hal ini dilakukan sebagai tolak ukur keakuratan permodelan selanjutnya.
Hasil simulasi menunjukkan kapasitas tarik maksimum sambungan sebesar 307,48 kN, terbagi pada dua rod dengan kapasitas masing - masing 153,74 kN pada displacement 23,2 mm dan tegangan 925,08 MPa. Sedangkan kapasitas geser maksimum pada masing - masing shear key mencapai 305 kN pada displacement 2,5 mm dengan tegangan 405 Mpa. Rod mengalami deformasi elastis hingga Fy = 900 MPa, dilanjutkan fase plastis hingga mendekati Fu = 1100 MPa, yang menyebabkan regangan permanen dan necking. Pada uji geser, shear key mengalami plastisitas total dan bearing failure di sekitar lubang.

The performance of high-rise modular steel structures is greatly influenced by the inter-module connection mechanism. The use of connections with a translational spring model approach to transfer loads between modules is proposed. This involves the use of threaded steel rods and shear keys that function to lock the movement between columns. The objective of this study is to determine the maximum tensile and shear capacity, stress distribution, and failure mode of the modular inter-module connections.
The methodology used in this study is numerical FEM analysis with the application of monotonic loads. Model validation is based on previous research, which serves as a benchmark for the accuracy of subsequent modelling.
The simulation results show that the maximum tensile capacity of the connection is 307.48 kN, divided between two rods with capacities of 153.74 kN each at a displacement of 23.2 mm and a stress of 925.08 MPa. Meanwhile, the maximum shear capacity of each shear key reached 305 kN at a displacement of 2.5 mm with a stress of 405 MPa. The rod underwent elastic deformation up to Fy = 900 MPa, followed by a plastic phase up to nearly Fu = 1100 MPa, causing permanent strain and necking. In the shear test, the shear key experienced total plasticity and bearing failure around the hole.
