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:
Combined with the shaking table test of SRC frame and the results of Pushover analysis, the failure mechanism of "strong column and weak beam" in the actual SRC column-steel beam composite frame is studied. From the two aspects of the incongruity of the seismic code control of the mechanism of reinforced concrete frame and steel frame "strong column weak beam" and the difference between steel beam and SRC column in seismic characteristics itself, the shortcomings of the realization of the "strong column and weak beam" failure mechanism of the composite frame and the shortcomings in the adjustment of internal force are demonstrated, and it is proposed that the realization of the "strong column and weak beam" of the steel beam-SRC column composite frame should be adjusted according to the ultimate bearing capacity and designed with the corresponding internal force adjustment coefficient of the reinforced concrete primary frame. This paper points out the problems that need to be paid attention to when performing finite element simulation of SRC components.
