Abstract

Gempa bumi merupakan bencana yang dapat menimbulkan getaran secara tiba-tiba sehingga dapat menyebabkan kerusakan infrastruktur. Adanya gempa bumi, bangunan diharuskan stabil dan tidak mengalami kegagalan struktur. Sistem desain yang efektif untuk membangun bangunan salah satunya adalah sistem isolasi seikmik. Sistem desain yang termasuk sistem isolasi seikmik adalah isolasi antar tingkat. Tujuan penelitian ini yaitu mengetahui sistem desain isolasi bertingkat yang paling efisien dalam membangun bangunan dengan kinerja struktur tahan bahaya gempa bumi. Metode yang digunakan pada penelitian ini adalah permodelan sistem isolasi antar tingkat dengan peletakkan pada masing-masing lantai. Berdasarkan penelitian diperoleh hasil struktur bangunan A dan bangunan B aman untuk semua lantai pada arah X dan Y. Respon struktur dengan adanya penambahan sistem isolasi triple friction pendulum pada bangunan A yang isolatornya diletakkan di lantai 1 dan 5 memiliki periode yang terbesar dibandingkan dengan peletakan isolator yang lain yaitu sebesar 2.603 sec. Kinerja batas layan bangunan A memiliki nilai optimum sebesar 2.486 mm yang isolatornya di lantai 5 dan 7. Kinerja batas ultimate bangunan A memiliki nilai optimum sebesar 3.71 mm yang isolatornya di lantai 7 Dengan demikian maka dapat disimpulkan bahwa perbandingan dan evaluasi yang lebih konkrit untuk meminimalisir kerusakan pada bangunan serta memberikan kenyamanan bagi penghuni yaitu bangunan A dengan perletakan isolator di lantai 5 dan lantai 7.

An earthquake is a disaster that can cause sudden vibrations that can cause damage to infrastructure. In the presence of an earthquake, the building must be stable and not experience structural failure. One of the effective design systems for constructing buildings is the seicmic isolation system. The design system which includes a seicmic isolation system is isolation between levels. The aim of this study is to determine the most efficient multilevel isolation design system in constructing buildings with earthquake resistant structural performance. The method used in this research is to model the isolation system between levels by laying it on each floor. Based on the research, the results obtained that the structure of building A and building B are safe for all floors in the X and Y directions. The response of the structure with the addition of a triple friction pendulum isolation system in building A, where the insulators are placed on the 1st and 5th floors, has the largest period compared to the placement another insulator that is equal to 2,603 sec. The performance of the service limit of building A has an optimum value of 2,486 mm for which the insulator is on the 5th and 7th floors. The performance of the ultimate limit for building A has an optimum value of 3.71 mm for which the isolator is on the 7th floor. Thus it can be concluded that comparisons and evaluations are more concrete to minimize damage in buildings and provide comfort for residents, namely building A with isolator placement on the 5th and 7th floors
