ANALISIS PERPINDAHAN GEDUNG BETON BERTULANG TINGKAT RENDAH TERHADAP BEBAN GEMPA SESUAI PETA GEMPA 2017 DENGAN ANALISIS RIWAYAT WAKTU
Abstract
Indonesia is one of the countries that frequently experiences earthquakes and results in structural failure. The structure used in this study was in the form of a low-rise building which was studied by placing the building in 99 major cities in Indonesia with a class of SC, SD and SE soil sites. This study uses a time history analysis method in assessing the inter-floor displacement of structures when receiving 3 earthquake histories in each city and the class of soil sites. The earthquake recordings used in the study were obtained from the peerberkeley.edu website which was then adjusted for spectrum response in each city and soil site class with the help of the SeismoMatch program. The earthquake recordings used were the Parkfield earthquake (1966), Parkfield (1996), and Southern Calif (1952) for SC soil, Humbolt Bay earthquake (1937), Imperial Valley (1938), and Northwest Calif (1941) for SD soil, and earthquake Imperial Valley-06 (1979), Youtnville (2000), and Imperial Valley-07 (1979) for soil SE. This study uses the SAP2000 version 21 program in modeling the review structure. Foundation of this study is assumed to be the foundation of foot plate and modeled as a joint springs in the SAP2000 program. The inter-floor displacement obtained from the structure is limited by a permit displacement of 2% from the inter-floor height in accordance with SNI 1726: 2012 Table 16. The results of this study indicate that there are 2 cities with SE land class sites that produce displacement on the ground floor beyond permits, namely in the city of Padang Sidempuan and the city of Sungai Penuh
