Abstract:: Based on the result of shaking table test and Pushover analysis of SRC frame，the problem thatstrong column—weak beam failure mechanism is difficult to realize in practical composite flame is studied fromtwo aspects：the regulations incoordination on strong column—weak beam between reinforced concrete flameand steel frame and the seismic properties difference between steel beam and SRC column，basic defect anddeficiency of norm provision on internal force adjustment is demonstrated．Suggestions about internal force ad—justment coefficient for strong column-weak beam realization of composite flame and the imulation of SRCmembers are proposed．
