RESEARCH ON THE RESPONSE MODIFICATION FACTORS OF CBSF

摘要：

In this paper, the definition and computation method of response modification factor(behavior factor) is firstly explained, and then a V concentrically braced steel frame(CBSF) and an inverted-V CBSF were designed according to Chinese design codes,after that, the incremental dynamic analysis (IDA) was used to get the response modification factors. The results indicated that whether the connections between braces and columns or beams are rigid or hinged, which does not have much influence on the response modification factors of the structures. But the different seismic wave may bring different response modification factors for the same structures. Furthermore, the analysis method, limit state, failure criterion and finite element model of structures have some influence on the response modification factors of structures, and much work was needed in this research field.
