Abstract

Buildings with plans using previous standardization are one of the highlights, where we know PPIUG 1983 is an old rule for earthquake resistant building planning and has been replaced by a new planning regulation, namely SNI 03-1726-2012 which is based on international. ASCE 7-10 code and has been renewed again with the issuance of SNI 03-1726-2019 which is also based on ASCE 7-16 code. Based on this, the researcher will analyze the performance level of the existing Griya Niaga 1 CIMB Niaga Bintaro building. By using the Pushover Analysis method based on the criteria of the Performance Based Objective Excisting Building from ASCE 41-17 with an earthquake loading design according to ASCE 7-10. Evaluation of the performance of the structure is carried out using the Displacement Target Method in accordance with the results of the Pushover analysis obtained. By simulating the building structure in 3D modeling using the ETABS v16.0 application program with structural data in accordance with the As Built Drawing of the existing building. The level of performance of the structure targeted is in accordance with the function of the building being reviewed, namely Life Safety. By looking at the results of the pushover analysis in the form of a roof displacement of 307,200 mm in the direction of x and 313,933 mm in the direction of y, as well as the roof shear limits for the level of structural performance at x and y. direction, obtained the level of performance of the building structure (Gedung Griya Niaga 1, CIMB Niaga Bintaro) in accordance with the acceptance of ASCE 41 - 17 regulations, namely the Structural Performance Level of Damage Control in the x direction and Reduce the Structural Performance Range of Safety (S - 4) towards y. Keywords : Pushover, ASCE 41-17, Performance Level Bangunan dengan perencanaan menggunakan standarisasi terdahulu menjadi salah satu sorotan khusus, dimana kita ketahui PPIUG 1983 merupakan peraturan lama untuk perencanaan bangunan tahan gempa dan sudah digantikan dengan peraturan perencanaan baru yaitu SNI 03-1726-2012 yang didasarkan pada kode peraturan internasional ASCE 7 – 10 dan sudah dilakukan pembaruan lagi dengan dikeluarkannya SNI 03-1726-2019 yang mana didasari juga dari kode peraturan ASCE 7 – 16. Dan seperti yang sudah diketahui, di dalam SNI 1726 ataupun ASCE 7 resiko gempa pada perencanaan struktur di desain lebih besar dibandingkan peraturan terdahulu. Berdasarkan hal tersebut, peneliti akan menganalisa performance level excisting building dari Gedung Griya Niaga 1, CIMB Niaga Bintaro. Dengan menggunakan metode Pushover Analysis dengan berdasarkan kriteria Based Performane of Objective Excisting Building dari ASCE 41 – 17 dengan desain pembebanan gempa sesuai ASCE 7 – 10. Evaluasi kinerja struktur dilakukan dengan menggunakan Metode Target Perpindahan sesuai dengan hasil analisa Pushover yang didapat. Dengan mensimulasikan struktur bangunan pada permodelan 3D menggunakan program aplikasi ETABS v16.0 dengan data struktur sesuai dengan As Built Drawing bangunan eksisting. Tingkat kinerja struktur yang ditargetkan sesuai dengan fungsi bangunan yang ditinjau, yaitu Life Safety. Dengan melihat hasil analisa Pushover berupa perpindahan atap sebesar 307,200 mm pada arah x dan 313,933 mm pada arah y, serta batas – batas perpindahan atap untuk tingkat kinerja struktur pada arah x dan y, maka didapat tingkat kinerja struktur bangunan (Gedung Griya Niaga 1, CIMB Niaga Bintaro) sesuai penerimaan pada peraturan ASCE 41 – 17 adalah Damage Control Structural Performance Level pada arah x dan Reduce Safety Structural Performance Range (S – 4) pada arah y. Kata kunci : Pushover, ASCE 41 – 17, Tingkat Kinerja
