英文摘要	Selection and modification of recorded earthquake ground motions is one of the most important issues for reliable seismic performance evaluation of the structure. In order to investigate the influence of ground motion spectral shape on nonlinear seismic response and to find the implication for ground motion selection and modification, a 3-storey RC planar frame is taken as case study in this paper. 15 ground motion records are chosen from PEER Ground Motion Database and Wenchuan Great Earthquake as dynamic analysis inputs. First, all selected ground motion records are scaled to have the same spectral acceleration at the first-mode period of the structure Sa (T1) and dynamic nonlinear analysis is conducted on the frame. The results show that engineering demand parameters such as maximum roof displacement δroof, max and maximum inter-story drift ratio θmax of the frame under ground motion input has the good correlation with the corresponding spectral acceleration at the higher mode period of the frame such as Sa (T2) and Sa (T3). Then, different scaling factor is used to scale the ground motion to have different Sa (T1) and incremental dynamic analysis is conducted on the frame. The results show that the variability of engineering demand parameters such as δroof, max and θmax becomes more obvious with the increase of Sa (T1). © (2012) Trans Tech Publications.
