The RTGM adopts 1% probability of building collapse in 50 years, introducing a risk-coefficient. Risk-coefficient is defined as ratio of RTGM and maximum considered earthquake (MCE) hazard adopting 2% probability of exceedance in 50 years. The RTGM integrates hazard curve and building fragility, with a logarithmic standard deviation, β, value. This paper presents sensitivity analysis on hazard curves and β-values of six (6) specific sites in Indonesia. The hazard curves are represented by various seismic source conditions representing both subduction and shallow crystal zones with various level of intensities. This is obtained from recent probabilistic seismic hazard analysis conducted for revision of Indonesian seismic hazard maps. β-values are varied representing variation of building qualities. The sensitivity analysis is conducted for two spectral accelerations at periods of 0.2-second (short) and 1second period. The analysis shows that there is about 7-14% deviation in risk coefficient values resulted from 0.6-0.8 variation in β-value and about 18-34% deviation resulted from 0.6-1.0 variation in β-value. Use of β value of 0.7 in the current Indonesian code is considered to be acceptable.
