We have studied the behavior of Hybrid Structure with reinforced concrete core wall-perimeter steel frame under dynamic and static loads with incremental dynamic analysis(IDA) and static pushover analysis. Three different storey models, 12-storey, 20-storey and 30-storey with diagonally-braced frame have been analyzed. Twenty seismic ground motion records(LA1-LA20, FEMA) can be used to obtain an average response optimally in IDA. We have compared the storey drift angle(SDA) between IDA(ten different intensities, PGV from 10kine to 100kine) and static pushover analysis to estimate more thoroughly structural performance with plastic development; additionally, we have discussed the interstorey shear force amplificatory ratio y between IDA and static pushover analysis, found it's quite related to the input intensity and location along the building. Finally we have discussed the ratio a to obtain the change rule about the ratio y of frame and wall towards the ratio y of total storey.
