Abstract

Indonesia merupakan wilayah dengan tingkat aktivitas seismik yang tinggi sehingga perancangan struktur bangunan tahan gempa menjadi aspek penting dalam rekayasa struktur. Struktur baja dengan Sistem Rangka Pemikul Momen (SRPM) memiliki daktilitas yang baik, namun kerusakan akibat gempa umumnya terjadi pada elemen utama yang sulit diperbaiki. Salah satu alternatif untuk mengatasi permasalahan tersebut adalah penggunaan replaceable shear link sebagai elemen pelebur (structural fuse) yang dirancang untuk melokalisasi kerusakan pada elemen yang dapat diganti. Penelitian ini bertujuan membandingkan perilaku struktur portal baja konvensional dengan struktur portal menggunakan balok non-prismatik dan replaceable shear link pada konfigurasi 3, 6, dan 9 lantai. Penelitian dilakukan secara numerik menggunakan ETABS v22 dan ABAQUS. Struktur dirancang berdasarkan AISC 360-16, AISC 341-16, AISC 358-22, ASCE 7-16, Design Guide 39, serta prosedur desain oleh Fanaie et al. (2024). Analisis struktur global dilakukan menggunakan analisis respons spektrum dan pushover, sedangkan perilaku lokal replaceable shear link dianalisis menggunakan metode elemen hingga dengan pembebanan monotonik. Hasil penelitian menunjukkan bahwa replaceable shear link mampu melokalisasi deformasi plastis pada elemen shear link, sementara balok dan kolom tetap berada dalam kondisi elastis. Hasil pushover juga menunjukkan bahwa sendi plastis pertama terbentuk pada replaceable shear link dan berkembang hingga tingkat kinerja Collapse Prevention tanpa menyebabkan kerusakan pada struktur utama. Dibandingkan portal konvensional, penggunaan replaceable shear link mampu menurunkan perpindahan atap hingga 17,79% serta meningkatkan kapasitas disipasi energi hingga 33,2% pada konfigurasi tertentu. Namun, implementasinya juga menyebabkan penurunan kekakuan lateral struktur sebesar 14–23%. Secara umum, penggunaan replaceable shear link efektif dalam melokalisasi kerusakan dan meningkatkan kapasitas disipasi energi pada struktur portal baja.

Indonesia is a region with a high level of seismic activity, making the design ofearthquake-resistant building structures a critical aspect of structural engineering. Steelstructures using a Moment-Resisting Frame System (SRPM) exhibit good ductility;however, earthquake-induced damage typically occurs in primary structural elements thatare difficult to repair. One alternative to address this issue is the use of replaceable shearlinks as structural fuses designed to localize damage to replaceable elements. This studyaims to compare the behavior of conventional steel portal frames with portal frames usingnon-prismatic beams and replaceable shear links in 3-, 6-, and 9-story configurations. Thestudy was conducted numerically using ETABS v22 and ABAQUS. The structures weredesigned in accordance with AISC 360-16, AISC 341-16, AISC 358-22, ASCE 7-16, DesignGuide 39, and the design procedures by Fanaie et al. (2024). Global structural analysis wasperformed using response spectrum and pushover analyses, while the local behavior of thereplaceable shear link was analyzed using the finite element method with monotonic loading.The results of the study show that the replaceable shear link is capable of localizing plasticdeformation within the shear link element, while the beams and columns remain in an elasticstate. The pushover results also indicate that the first plastic hinge forms at the replaceableshear link and develops to a kinematic level Collapse Prevention without causing damage tothe main structure. Compared to conventional portal frames, the use of replaceable shearlinks can reduce roof displacement by up to 17.79% and increase energy dissipation capacityby up to 33.2% in certain configurations. However, their implementation also results in a14–23% reduction in the structure’s lateral stiffness. In general, the use of replaceable shearlinks is effective in localizing damage and increasing energy dissipation capacity in steelportal structures.
