摘要:
结合SRC框架振动台试验和Pushover分析结果,针对实际SRC柱-钢梁组合框架不易出现"强柱弱梁"破坏机制的问题进行了研究.从抗震规范对于钢筋混凝土框架和钢框架"强柱弱梁"机制控制的不协调和钢梁与SRC柱在抗震特性本身的差异两方面,论证了组合框架"强柱弱梁"破坏机制的实现在规范方面存在基础上的缺陷以及内力调整方面存在的不足,提出了钢梁-SRC柱组合框架"强柱弱梁"的实现宜按照极限承载力进行调整并以钢筋混凝土一级框架相应的内力调整系数进行设计的建议,指出了对SRC构件进行有限元模拟时需注意的问题.
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．
