Abstract

The high-rise building of steel structures requires strengthening system so that buildings are capable of carrying earthquake loads that may occur. Strengthening of steel structure building can be applied by providing stiffness of the structure in the form of mounting lateral stiffening system using eccentrically braced frame or concetrically braced frame. The purpose of this study is to analyze performance of story drift of the building structure in the form of horizontal drift values due to earthquake load on the building structure using the stiffening lateral x-braced frame and the two story x-braced frame. The research method using load of dynamic earthquake response spectrum analysis in accordance to SNI 03-1726-2012. The building models have 12 floors, located in Lampung city and was planned behave as an Intermediate Moment Resisting Steel Frame (IMRSF). Building model was designed and anlyzed using ETABS Version 9.7. This study shows story drift in type two story x-braced frame is smaller than the x-braced frame.

Abstract

Rangka Terbreis Eksentris (RTE) merupakan sistem bangunan tahan gempa yang mempunyai keunggulan dari segi kekuatan dan kekakuan serta mempunyai daktilitas dan kemampuan energi disipasi yang baik dalam kondisi inelastis. Link adalah elemen penting yang berfungsi untuk mendisipasikan energi gempa melalui perilaku inelastis struktur. Kinerja link geser berupa kekuatan, kekakuan, daktilitas dan disipasi energi tergantung pada profil penampang yang digunakan pada link. Kajian ini bertujuan untuk mengetahui perilaku struktur RTE dengan link menggunakan sambungan baut yang menggunakan variasi mutu baja serta pelebaran ujung pelat sayap (Side Extended Plate/SEP) dan tanpa SEP. Analisis dilakukan dengan menggunakan menggunakan software MSC PATRAN/NASTRAN. Sebanyak 8 (delapan) variasi model link dikaji untuk menentukan kinerja struktur yang paling optimum ketika dilakukan pembebanan statik monotonik dan siklik dengan kontrol perpindahan. Hasil menunjukkan bahwa variasi mutu baja link pada pelat sayap dan pelat badan dapat meningkatkan kekuatan, kekakuan, dan daktilitas struktur secara signifikan dibandingkan dengan penggunaan SEP. Kata kunci : Rangka Terbreis Eksentis (RTE), link geser, link sambungan baut dan las, variasi mutu baja, pelebaran pelat sayap
