摘要
以实际算例分析了在美国北岭地震和日本阪神地震中 ,数百幢多高层钢结构房屋的梁柱刚性连接节点受到严重破坏的根本原因 ,提出在钢结构梁柱节点抗震设计中必须遵守的两个基本原则 ,同时还推荐了几种具有良好抗震性能的梁 -柱刚性连接节点。
The damage of column beam rigidity joints in hundreds of multi story and high steel buildings in the Northridge earthquake and the Hanshen earthquake is analyzed by a calculating example. The strong joint principles which must be complied with in aseismatic design are presented. The authors also recommend some kinds of column beam joints which have good aseismatic characteristics, such as welding slabs on the flanges in the beam's end, widening the width of the flanges in the beam's end, heightening the height of the beam in its end.
