The purpose of earthquake resistance design of building is to produce a structures that can withstand a certain level of a ground shaking without excessive damage. Careful consideration in the design of structures and facilities to the seismic are implemented by design of ground-motions. Jakarta as the capital city of Indonesia has potential of seismic hazard. Thus, design of high rise buildings in Jakarta requires reliable seismic design criteria for the safety and cost-effectiveness of the construction. Site-specific response analysis with reference to SNI-1726-2012 and generation of pairs of ground-motions with reference to FEMA-1050- 2015 of a proposed high-rise building site in Jakarta has been conducted. Through PSHA, two hazard levels of earthquake have been developed, that is representing 50% probability of exceedence (PE) in 30 years (43 years earthquake return period) and 2% PE in 50 years (2,475 years earthquake return period) ground-motions at reference base-rock (Sb). In addition, risk-targeted ground-motions (RTGM) defined as 1% probability of the building collapse in 50 years has been also developed adopting P-value = 0.65. Seven pairs of ground- motions time-history have been generated with spectral periods scaling from 0.2-10.0 sec considering seismic sources from Megathrsut, Beniof and Shallow Crustals have been applied to consider the short and long period motions have potential to hit the proposed building with structure period of 7.0 second.
