Abstract

Sistem Rangka Bresing Eksentrik (SRBE) merupakan sistem yang mensyaratkan perilaku inelastik hanya terjadi pada balok link sedangkan elemen lainnya masih dalam konsisi elastis. Kondisi link yang menyatu dengan balok mengakibatkan link mengalami overstrength karena harus menahan beban yang sama seperti balok induk. Selain itu, pergantian pasca gempa yang harus dilakukan dengan mengganti keseluruhan elemen balok dinilai kurang efisien sehingga digunakan replaceable link yang dapat dibongkar hanya pada bagian balok link saat terjadi kerusakan. Struktur portal SRBE dengan kriteria balok link yaitu link pendek, link menengah, dan link panjang dimodelkan dalam penelitian ini menggunakan program bantu ETABS V21. Analisis dilakukan terhadap model bangunan 10 lantai dengan variasi berupa panjang link menggunakan analisis nonlinear pushover. Spesimen yang diteliti berupa link yang tersusun dari profil WF. Kinerja replaceable link yang ditinjau yaitu kapasitas, daktilitas, energi disipasi, dan failure mode. Hasil penelitian menunjukkan bahwa variasi link yang memiliki kinerja terbesar yaitu link pendek dengan konfigurasi tebal pengaku yaitu 10 mm berjarak 160 mm sebanyak 5 buah.

The Eccentrically Braced Frame (EBF) structural system is a system that requires inelastic behavior to only occur in the link beam while the other elements are still in elastic condition. The condition of the links that are fused with the beams results in the links overstrength because they must withstand the same load as the main beam. In addition, post-earthquake replacement that must be done by replacing the entire beam element is considered inefficient, so replaceable links are used that can be replaced only in the link beam section when damage occurs. EBF with link beam criteria of short link, intermediate link, and long link were modeled in this study using the ETABS V21. The analysis was performed on a 10-story building model with variations in link length using nonlinear pushover analysis. The specimens studied were links composed of WF profiles. The performance of the replaceable link reviewed is capacity, ductility, energy dissipation, and failure mode. The results show that the link variation that has the greatest performance is the short link with a stiffener thickness configuration of 10 mm spacing 160 mm as many as 5 pieces.
