Abstract
Gempa bumi besar sering terjadi di Indonesia. Untuk meningkatkan performa bangunan serta menghindari keruntuhan, alat peredam pasif tambahan Tuned Mass Damper (TMD) dapat diterapkan pada struktur. Dalam studi ini, gedung yang semula menggunakan dinding geser untuk menyediakan performa seismik diubah menjadi gedung rangka pemikul momen dan dilengkapi dengan TMD. Dengan menggunakan program bantu SAP2000 dan ETABS, dua buah model bangunan didesain dan dianalisa respon strukturnya. Hasil analisa menunjukan bahwa kedua sistem sturktur telah memenuhi semua kriteria desain yang disyaratkan oleh peraturan gempa Indonesia SNI 1726:2012. Pada struktur rangka momen, TMD dengan rasio massa 0,6% telah mampu meningkatkan kinerja seismik stukrtur sehingga mencapai batas aman. Adapun studi komparasi yang dilakukan menunjukan bahwa struktur dual system dalam semua kriteria desain yang ditinjaun, memiliki performa lebih baik dari struktur TMD. Salah satu yang menjadi perhatian utama dalam analisa yakni deformasi struktur. Dengan adanya kekakuan besar yang disediakan oleh dinding geser, struktur dual system memiliki deformasi yang lebih kecil ketimbang struktur rangka+TMD.
===============================================================
Earthquake commonly occurs in Indonesia. To avoid the collapsing of building and to provide the best performance under a heavy earthquake, Tuned Mass Damper (TMD) can be implemented in structure. In this research, the building structure which is originally use sheer wall as an earthquake resisting component will become an object. Sheer wall component in the original building will removed, and as a compensation, TMD device will utilized and placed at a top floor of the building. Using computer simulation program SAP2000, two building model, original building-sheer wall system and new ordinary frame building system equipped with TMD are observed. Some building responses, i.e. ‘Floor Deformation and Drift’, ‘Inertial Forces’, ‘Base Reaction’, and ‘Service limit and Ultimate Limit Performance’ of two building model are observed and compared. The result show that the building with 0,6% TMD can effectively control all the responses and has better performance compare to building-sheer wall system in three variable, i.e. ‘Base Reaction’, ‘Inertial Forces’, and ‘Service and Ultimate Limit Performance’. Due to its great stiffness providing by sheer wall component attached in the structure, building-sheer wall system can control ‘Floor Deformation and Drift’ response better than TMD-System.
