摘要
本文分析了半刚性连接组合梁框架的在水平荷载作用下的受力特性,提出了对于具有合理构造措施的半刚性连接框架,采用塑性分析方法进行在水平荷载作用下的框架整体极限承载能力、组合梁的承载能力及框架柱的承载能力验算。采用塑性分析方法可使设计计算工作量极大地降低,而且能给出较为安全和准确的分析结果,这可供半刚性连接框架的实际设计参考。
In this paper, the behavior of semi-rigid frames consisting of steel-concrete composite beams and steel columns under lateral loading are analyzed, a simplified plastic method is deduced to predict the ultimate resistance of the overall frames,composite beams and steel columns. It is demonstrated that the plastic method can predict satisfactory results on the ultimute limit states of semi-rigid composite frames under lateral loading with much redution in calculation effort.
