PUSHOVER ANALYSIS FOR SRC FRAME
Pushover analysis is a simplified method for structural seismic evaluation, which is extensively used. For some problems on the determination of plastic hinge property, it is difficult to carry out Pushover analysis directly to steel reinforced concrete (SRC) structure, which is often substituted by reinforced concrete (RC) member with equal rigidity when Pushover analysis is needed. This paper presents the computing methods of N-M, M<,x>-M<,y> interrelated curves of SRC members theoretically, gives the determination means of M-ψ curve of SRC members, and puts forward the principle to form M-ψ curve of PMM hinge transformed from that of SRC member, all of which may be as a reference for SRC structure Pushover analysis. According to the proposed method in this paper, Pushover analysis is performed on a SRC frame with two bays and three stones, of which the results are in a good agreement with that of test. In the end, a comparative study is carried out between SRC frame and RC frame with equal rigidity based on the results of Pushover analysis, which demonstrates that the SRC structure has predominant seismic behavior to RC structure with the number of structure stories increasing.
