Development of earthquake risk-targeted ground motions for Indonesian Earthquake Resistance Building Code SNI 1726-2012

International Conference on Applications of Statistics and Probability (12th : 2015 : Vancouver, B.C.)

This paper presents recent efforts in the development of risk-targeted ground motions for the Indonesian Earthquake Resistance Building Code SNI 1726-2012. Recently, in 2010, the Indonesian seismic hazard map was revised by our Indonesian Team from the 2002 map to a new hazard map. The revised map has adopted the most recent data and current state of knowledge in probabilistic and deterministic seismic hazard assessment methodologies, and through the use of the most recent ground motion predictive equations. So-called risk-targeted ground motions (RTGM) have also been developed. The risk-targeted ground motions for Indonesia are calculated as spectral response accelerations that result in 1% probability of building collapse in 50 years through a similar methodology as conducted by Luco et al. (2007). The authors do so by adopting generic fragility curves with alogarithmic standard deviation, β, value considered to be representative of Indonesian buildings. The risk-targeted ground motions mapped for the whole of Indonesia have been developed for short and 1.0 second spectral periods. These maps have become the risk-targeted maximum considered earthquake (MCER) maps in the new SNI 1726-2012.
