| 摘 要： | 提出了翼缘开圆孔和翼缘、腹板均开孔的方钢管混凝土柱-钢梁削弱梁端新型节点形式．建立考虑几何非线性和材料非线性的有限元模型对此新型节点形式在单调及低周反复荷载作用下的受力性能进行数值分析，并和实验及传统的狗骨式节点（RBS）在荷载-位移曲线、节点削弱端应力分布、承载力、延性及耗能能力等方面进行对比．结果表明：此类削弱方式与狗骨式节点的刚度和承载力均基本相同；塑性铰均能外移至削弱区域；削弱节点表现出良好的廷性和耗能能力，具有较好的抗震性能．

| Abstract: | Two kinds of new concrete-filled steel square tubular column and reduced steel beam joints with holes in flange or flange and web is presented.The non-linear finite element models considering geometric large deformation and material nonlinear are established for these joints.Comparison between analysis and experimental results is made on load-displacement curves,the stress distribution of reduced beams,the limit load capacity,the ductility,and the dissipating energy ability between analysis results and expe... |
