摘要(Abstract):

为了研究某钢-混凝土组合结构构筑物关键节点的受力性能和破环机理,按照1:2.5的缩尺比模拟实际工程节点进行了节点的低周反复加载试验。本文介绍了关键节点试验过程,分析了组合节点的强度、延性、骨架曲线和滞回性能,根据试验分析结果提出了组合结构节点设计建议。
In order to verify the mechanical properties of the key joints of a certain special engineering of steel-concrete composite structure system,specimens with 1:2.5 scale are designed based on the actual engineering and tested under cyclic loading.The results of experimental study and theory analysis indicate that the composite joints have enough bearing capacity and good ductility property.Some reasonable suggestions are presented for design of steel-concrete composite structure system and joints based on experimental study.
