【摘要】：设计并制作了4个比例为1∶2的传统风格建筑钢结构双梁-柱中节点模型,通过低周反复荷载试验研究其抗震性能,得到了传统风格建筑钢结构双梁-柱中节点的破坏形态、滞回特性、延性等指标。研究表明:传统风格建筑钢结构双梁-柱中节点试件在加载过程中形成了上、下2个小核心区和中间短柱三个区域,其典型破坏形态是节点下核心区在压剪复合应力作用下的剪切破坏。试件变形以下核心区最大,其次为中间短柱。基于试验研究,利用有限元软件ABAQUS对其进行了非线性数值模拟分析,得到的节点破坏形态、应力分布及滞回曲线与试验结果较为吻合。
[Abstract]:Four middle joint models of steel structure with a ratio of 1: 2 are designed and fabricated. The seismic behavior of the model is studied by low cycle cyclic loading test. The failure form, hysteretic characteristics and ductility of the joints in the steel structures of traditional buildings are obtained. The results show that the specimens of the joints in the steel structures of the traditional buildings have been formed in the process of loading. The typical failure pattern of the two small core regions and three middle short columns is the shear failure of the core area under the joint under the combined stress of compression and shear. The core region below the deformation of the specimen is the largest. Based on the experimental research, the nonlinear numerical simulation of the intermediate short column is carried out by using the finite element software ABAQUS, and the failure patterns of the joints are obtained. The stress distribution and hysteresis curve are in good agreement with the experimental results.

【正文快照】： 传统风格建筑是当代设计建造的仿古建筑的统称,是我国建筑文化发展的必然阶段。由于对木材的过量采伐带来的森林植被破坏,使用木材建造传统风格建筑已不符合环境保护和可持续发展战略的要求,于是便产生了用其他建筑材料代替木材建造传统风格建筑的做法。在诸多材料中,钢材具有
