摘要
门式刚架轻型房屋钢结构在我国的应用越来越广泛,已积累了较多的工程经验,同时,在工程实践中也发现了一些需要对《门式刚架轻型房屋钢结构技术规程》(CECS102:2002)进行修改和补充之处。应用有限元软件分析了门式刚架的屈曲临界力和稳定极限承载力,通过ANSYS计算,研究了摇摆柱对门式刚架变截面柱计算长度的影响,比较分析了现行规范中变截面柱计算长度系数计算的误差,对现行规范中带摇摆柱门式刚架的计算长度系数放大公式进行了修正并对修正公式进行验算。
As steel structures of light-weight building with gabled frames have been widely used,there are lots of experiences about construction,and found some mistakes in 〈Technical specification for steel structure of light-weight building with gabled frames〉 which should be revised.The purpose of the thesis is to research the effective length factor of tapered columns of tapered gable portal frames with leaning columns,and to revise the corresponding specifications in 〈Technical specification for steel structure of light-weight Building with gabled frames.〉
