Abstract
Indonesia secara geografis termasuk dalam kawasan “Ring of Fire” yang memiliki intensitas bencana gempa bumi yang cukup tinggi. Untuk mengantisipasi kerusakan dan kegagalan struktur yang disebabkan oleh bencana gempa, maka diperlukan suatu alternatif dalam merencakanan suatu struktur bangunan tahan gempa. Salah satu alternatif dalam merancang bangunan gedung tahan gempa adalah dengan menggunakan struktur Eccentrically Braced Frame (EBF). Sistem struktur EBF merupakan sistem yang mensyaratkan perilaku inelastik hanya terjadi pada balok link selama pembebanan gempa sehingga link akan mengalami rotasi inelastik sedangkan komponen lainnya dari EBF tetap elastik. Terdapat tiga kriteria balok link yang dimungkinkan dalam sistem struktur EBF, yaitu short link, intermediate link dan long link yang ditentukan dari normalisasi panjang link dengan rasio antara kapasitas momen plastis (Mp) dan kapasitas geser plastis (Vp). Kinerja link yang mampu mendisipasi energi gempa ditunjukkan dengan kelelehan yang membentuk sudut rotasi inelastik yang cukup besar pada link saat struktur sudah mengalami deformasi yang besar akibat beban lateral (gempa). Kerusakan link akibat kelelehan inilah yang sebenarnya diharapkan terjadi, untuk menjadikan struktur memiliki daktalitas yang cukup tinggi. Pada tugas akhir ini, pembahasan mengenai struktur bangunan tahan gempa akan difokuskan pada perilaku yang terjadi akibat dari penerapan ketiga tipe balok link EBF (short link, intermediate link, dan long link) pada suatu struktur bangunan tahan gempa. Analisis dilakukan terhadap tiga model bangunan 10 lantai yang menggunakan sistem EBF tipe Split K-Braces dengan variasi panjang link.. Proses analisis struktur secara umum dilakukan dengan bantuan software ETABS, sedangkan untuk analisis mikro terhadap satu portal struktur EBF digunakan bantuan software ABAQUS. ======================================================================================================
Indonesia as geographically included within the "Ring of Fire" that has the intensity of earthquake is high enough. To anticipate the damage and structural failure caused by earthquake disaster, an alternative is needed in planning an earthquake resistant building structure. One alternative in designing earthquake resistant building is using Eccentrically Braced Frame (EBF) structure. The EBF structure system is a system that requires inelastic behavior to occur only in the link beam during earthquake loading so that the link will undergo inelastic rotation while the other components of EBF remain elastic. There are three possible link beam criteria in the EBF structure system, ie short links, intermediate links and long links determined from link length normalization with the ratio between plastic moment capacity (Mp) and plastic shear capacity (Vp). The performance of a link capable of dissipating earthquake energy is indicated by the melt that forms a substantial inelastic rotation angle at the link when the structure is already deformed substantially by lateral loads (earthquakes). In this final project, the discussion about the earthquake resistant building structure will be focused on the behavior caused by the application of the three types of EBF link beam (short link, intermediate link, and long link) in an earthquake resistant building structure. The analysis was conducted on three 10-storey building models using the Split K-Braces EBF system with variation of link length. The process of structural analysis is generally done with the help of ETABS, while for micro analysis of one portal EBF structure used software ABAQUS.
