摘要
分析了汶川地震中钢结构厂房钢管柱间支撑的震害原因,指出钢管直接焊接连接节点塑性变形能力差,引起应力集中而破坏。文中提出钢管柱间支撑节点构造的改进措施,供工程实践参考。
Earthquake disaster for steel-tube intercolumnar brace of steel structure factory buildings in the Wenchuan Earthquake is analyzed.Direct-welded joints of steel-tube are not provided with plastic deformation capability,and lead to damage by stress concentration.In the paper details of steel-tube intercolumnar brace are improved.
