【摘要】 通过对连续型钢混凝土梁式转换层结构模型的两种加载方式下的拟静力试验,对比分析了型钢混凝土转换节点与柱不带轴压力型钢混凝土框架节点的抗震特性,得到了不同于普通框架节点的转换节点的破坏机制、耗能能力、强度退化等.分析得出节点型钢腹板的剪应力方程,利用试验数据可求得腹板上测点的应力值.为了与试验结果相互验证,建立有限元模型,进一步对比分析证明了转换节点在地震力下的受力特性符合节点斜压杆机理.更多还原

【Abstract】 Based on the pseudo-static tests of the continuous steel reinforced concrete(SRC) beam transferring structural model under two loading modes,some aseismic behaviors of transferring joints,such as the failure patterns,deformation capacity,energy dissipation capacity,strength degradation of steel reinforced concrete transferring joints,were presented for contrasting them with the aseismic performance of SRC frame joints without axial compression.The aseismic behaviors of the SRC transferring joints and the equivalent SRC frame joints were analyzed by using the finite element method.Stresses in the steel webs were obtained by using the test data in the shear strength equation introduced from the analysis.In order to prove the results of the test,a finite element model was put forward,which showed that the strut-tie mechanism of the transferring joints under earthquake forces is effective.更多还原
