| 摘 要： | 为研究柱钢管不全贯通式钢管混凝土柱—梁节点的偏压性能,探讨了偏压试验中的节点试件的破坏形态、极限承载力及变形能力等情况,并采用DIANA软件进行参数化非线性有限元方法分析。试验及分析结果表明,节点具有较好的延性,节点方案是可行的。有限元分析可较好地模拟偏压试件的变形及极限承载力、裂缝开展以及钢筋应变分布规律。偏心距的增大会使得偏压试件承载力降低,配筋率的增大会使得偏压试件承载力提高,偏压构件的环筋应变沿受压侧向受拉侧衰减,形成不均匀的约束力。

| Abstract: | In order to study the eccentric compressive behavior of the CFST column-beam joint with the column tube discontinuous in joint zone,eccentric compressive experiments,including tests of the failure mode,ultimate capacity and the deformation of the specimens were done. DIANA software was used to carry out the parametric nonlinear finite element analysis (FEA) on the joint. The results indicated that the joint had good ductility and the type of joint was feasible. The FEA simula- ted well the deformation,ultim... |
