摘要:
对一棍SRC框架进行静力非线性分析,分析结果与试验吻合较好;在此背景下,通过对两跨三层的SRC柱-钢梁混合框架进行静力非线性分析,研究了SRC柱含钢率和梁柱线刚度比对混合框架抗震性能的影响.结果表明,SRC柱-钢梁底层框架实现了“强柱弱梁”破坏模式,混合框架荷载-位移曲线经历了较长的塑性变形阶段,结构表现出良好的整体延性.随着梁柱线刚度比增加,框架破坏模式逐渐从整体“强柱弱梁”过渡为“强梁弱柱"破坏模式,结构延性下降明显,设计时可取0.3~0.4作为参考的界限梁柱线刚度比.
Abstract:
In this paper,a static nonlinear analysis of SRC frame has been made,and the analytical results agree well with those of the tests. In the same parameter settings,the static nonlinear analysis of a 2-span,3story SRC column-steel beam hybrid frame is then carried out to learn its seismic performance when the steelratio of SRC column and linear stiffiness ratio of beam to column is different.The results show that the bottomstory of SRC column-steel beam hybrid frame achieve the strong column-weak beam failure mode,so the overall structure experienced a long plastic deformation stage and exhibited good ductility. With the increase of thelinear stiffness ratio of beam to column,the failure of hybrid frame gradually turned from the overall"strongcolumn-weak beam”mode into "strong beam-weak column"mode, and the structure ductility reduced Significantly.According to the calculation results,a reference value range 0.3 ~0.4 is suggested for line stiffnessratio of beam to column in SRC column-steel beam hybrid frame design.
