Kajian Numerik Sambungan Balok-Kolom Baja dengan Kuncian yang Dapat Diganti

During the Northridge and Kobe Earthquake, many steel moment resisting frames suffered damage at the beam-column connections. During these years methods were proposed by researchers which were mainly based on reducing the beam section or strengthening the connection. In this study, an innovative structural system with replaceable interlock was proposed. The main feature of this system is that plastic deformation is limited to the replaceable interlock. The monotonic test of the model using Abaqus/ Standards was carried out, compared with The Simpson Strong-Tie Strong-Frame (SSTSF) which is according to AISC 358-16 as partially restrained system with replaceable component. The analysis results demonstrated that the structural fuse and the whole structural behavior performed well. The interlock components have better strength and ductility than SSTSF. Furthermore, the replaceable interlock can play role of structural fuses by dissipating more than 86% of the input energy, which effectively protect the non-fuse components from damage.
