摘要
对高层钢结构经常采用的一种支撑连接节点进行研究。通过力学机制解析,指出此种节点存在承载能力不足的缺陷。采用数值分析方法,建立27个参数模型,根据分析结果,给出节点极限承载力与截面宽高比、翼缘宽厚比、腹板高厚比等各参数的关系,验证此节点承载能力不足的缺陷。最后给出此种支撑连接节点的改进措施。
One typical brace-frame joint usually used in the high-rise steel structures was researched by the mechanics analysis and numerical analysis method in the paper.Based on the mechanics analysis,the defect of bearing capacity was discussed.Finite element analyses were conducted on 27 joints of various parameters influencing joints behavior,such as section width-to-height ratio,flange width-to-thickness ratio,and web depth-to-thickness ratio.Based on the result of the numerical analysis,the defect was verified.Finally an improvement measure was given.
