Sandhi, Reza Dwipa (2017) Kajian Analisis Pushover Untuk Performance Based Design Pada Gedung Fakultas Ilmu Sosial Dan Politik (FISIP) Universitas Brawijaya. Sarjana thesis, Universitas Brawijaya.
Abstract
Analisa statis non-linear (pushover analysis) digunakan untuk mengetahui perilaku struktur akibat gempa besar. Pushover analysis merupakan salah satu performance based design dengan konsep memberikan suatu pola beban lateral statik terhadap bangunan secara bertahap sampai memenuhi target perpindahan lateral yang direncanakan. Hasil dari metode ini adalah kurva base shear-roof displacement yang selanjutnya diproses untuk menentukan titik kinerja (performance point) dan tingkat kinerja struktur dengan menggunakan dua prosedur berdasarkan ATC-40 1997 yaitu prosedur A dan prosedur B. Pada analisis ini dilakukan pemodelan dengan mengambil contoh jenis bangunan yaitu gedung fakultas ilmu sosial dan politik Universitas Brawijaya, lalu gedung tersebut dianalisis untuk mengetahui simpangan antar lantainya, tingkat kinerja dari bangunan, dan titik performa yang dihasilkan dengan dua macam respon spektrum desain berdasarkan SNI-1726-2002 dan SNI-1726-2012. Struktur bangunan dimodelkan sesuai gambar DED (Detail Engineering Design) dengan penyederhanaan yang diperlukan. Analisis dilakukan dengan menggunakan bantuan program SAP2000 v19 dan berdasarkan ketentuan yang ada di ATC 40 1997. Hasil yang diperoleh dari pushover analysis ini untuk prosedur A adalah dimana dihasilkan titik performa (0.315, 0.0602) untuk gempa desain respon spektrum SNI-1726-2002 dan (0.205, 0.0379) gempa desain respon spektrum SNI- 1726-2012. Sedangkan titik performa (performance point) untuk prosedur B dimana dihasilkan titik performa (0.277, 0.08) untuk gempa desain respon spektrum SNI- 1726-2002 dan (0.184, 0.053) gempa desain respon spektrum SNI-1726-2012. Mekanisme runtuh yang terjadi dimulai dari balok terlebih dahulu baru kemudian kolom sehingga bangunan masih relatif aman untuk dihuni (beam sidesway mechanism). Berdasarkan ATC-40 1997 semua hasil analisis baik prosedur A maupun prosedur B dengan dua peraturan berdasarkan SNI 2002 dan 2012 tingkat kinerja struktur bedasarkan deformasi menunjukan bahwa struktur berada dalam fase Immediate Occupancy.
English Abstract
Non-linear static analysis (pushover analysis) is used to determine the behavior of structures due to large earthquakes. Pushover analysis is a performance based design with the concept of providing a static lateral load pattern to the building gradually to fulfill the planned lateral displacement target. The result of this method is the base shear-roof displacement curve which in the next step is processed to determine the performance point and the performance level of the structure using two procedures based on ATC-40 1997 (procedure A and procedure B). In this analysis, modeling is done by taking the example of the type of building that is the faculty of social and political science of Brawijaya University, then the building is analyzed to know the inter-floor drift, the performance level of the building, and the performance point produced with two kinds of response spectrum design based on SNI-1726 -2002 and SNI-1726-2012. The building structure is modeled according to the DED (Detail Engineering Design) drawings with the necessary simplification. The analysis was performed using the SAP2000 v19 program and based on ATC 40 1997. The results obtained from this pushover analysis for procedure A are the resulting performance point (0.315, 0.0602) for the spectrum response design based on SNI-1726-2002 and (0.205, 0.0379) for the spectrum response design based on SNI-1726-2012. While performance point for procedure B where produced performance point (0.277, 0.08) for spectrum response design based on SNI-1726- 2002 and (0.184, 0.053) spectrum response design based on SNI-1726-2012. The collapse mechanism that occur starts from the beam first and then the column so the building is still relatively safe to live (beam sideway mechanism). Based on ATC-40 1997 all analysis results of both procedure A and procedure B with two regulations based on SNI 2002 and 2012, the performance level of structures based on deformation indicates that the structure is in the phase of Immediate Occupancy.
