[摘要] 应用ABAQUS有限元分析软件，考虑了几何非线性、材料非线性、接触非线性、包辛格效应、焊缝缺陷、高强螺栓的预拉力等多种因素的影响，对蜂窝钢框架梁柱节点和腹板开孔钢框架梁柱节点的承载能力、破坏模式、延性性能和耗能能力进行了分析。研究表明：普通蜂窝钢梁柱节点的延性较差，故其不适宜直接用于抗震结构中；腹板开孔钢梁框架通过调整钢梁孔洞大小和孔洞间距可以有效地改善梁柱节点的延性性能和耗能能力并应用于抗震结构中。上述初步分析结论需要进一步通过试验验证。

Abstract: Finite element analyses on capacity, failure pattems, ductility and energy dissipation of cellular beam and fabricated perforated beams to column connection had been executed by using ABAQUS. The geometric nonlinearity, material nonlinearity,contact nonlinearity, bausclunger effect, weld defects and pre-tension of high strength bolts were all taken into account. Analyses results show that cellular beam to column connection can not provide enough ductility and energy dissipation, so it is not suitable for directly used in moment frames. Ductility and energy dissipation of fabricated perforated beams to column connection can be improved and used in moment frames by adjusting the diameter and space of the hole. The preliminary conclusion need further experimental verification.
