초록

To obtain reliable results for time history analysis of structure under earthquake loads, it is required to selecting proper input ground motions and constructing numerical model for the structure. Especially, for high-rise or irregular building, structural engineers should conduct three dimensional dynamic analysis. The purpose of this study was to evaluate of seismic design criteria for selecting ground motions to conducting three dimensional time history analysis of structures. For this purpose, 134 earthquake records which are composed of two horizontal ground motions, respectively, were collected. Then, several three dimensional time history analyses for 3, 9-story steel moment resisting structures with or without irregularities. Input ground motions were selected according to KDS 41 17 00 criteria for design ground motions using proposed method from a companion paper. The results show that one can predict seismic responses of three dimensional structure within an error of 20% using more than 10 ground motions. However, if less than 7 ground motions are used, the responses may be overestimated.
