Seismic time-history ground-motions for a specific site in Jakarta

Indonesia has developed new seismic building code based on risk-targeted ground-motions adopting 1% probability of building collapse in 50 years. the new seismic design criterion,which is presented in the code,have combined both seismic hazard and building fragility. for performance-based analysis of high-rise buildings,a complex non-linear time-history analysis is needed. this paper presents results of study on development of the time-history with emphasing on procedure of developing pairs of time-history at ground surface for spesific site in jakarta with reference to 2012 international building codes and asce-sei-7-10. the study involves generation of time-history from reference base-rock through site-response analysis to ground surface. development of time-history at ground surface with a procedure involving square root of the sum of the square method (srss) in order to reasonably scaled time-histories through spectral matching technique is presented herein. the matched time-histories are developed from various strong-motion records representing different earthquake sources dominant to control the site evaluated from de-aggregation within seismic hazard analysis. this work also adopts baseline corrections in which velocity and displacement components of matched time-histories can be drifted to zero at the end of recorded seismic time. © 2015penerbit utm press. all rights reserved.
