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进行拟静力试验,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,得到了区别于普通框架节点的转换节点破坏机制、耗能能力、强度退化等.建立有限元模型,进一步对比分析,证明了转换节点在地震作用下的受力特性符合节点斜压杆机理,建立了型钢混凝土节点抗剪受力模型.
Based on the two loading modes pseudo-static test of the continuous steel reinforced concrete （SRC） beam transferring structural model, 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 by comparing the aseismic performance of the SRC frame joints without axial compression . A finite element model was put forward, which showed that the strut-tie mechanism of the transferring joints under the earthquake forces is effective. The mechanics model of shear resistance of the SRC joints was also established.
