Earthquake lateral force analysis of reactor building, experimental power reactor

Abstract

Indonesia is considering to construct its first experimental power reactor. Similar to other conventional nuclear power plants, this type of reactor is designed and built to withstand external hazards such as an earthquake. The seismic resistance design standard for building (SNI 03-1726-2012) as basic guidance should be implemented and used for earthquake-resistant building design. In this paper, a reactor building is considered for earthquake lateral force analysis to determine the design base shear force. In general, this analysis performed statically and dynamically. For static analysis, the equivalent lateral force method were used, while for dynamic analysis, the response spectrum method is used. The results of this study have shown that the value of displacement by using static analysis is more significant than the value of displacement by using dynamic analysis. It can be concluded that although the dynamic analysis is more accurate, the static analysis would lead to a more conservative result.
