| 摘 要： | 采用中性平衡法分析了5榀铰接门式刚架的稳定性,通过理论分析和规范方法计算了刚架柱的计算长度系数.计算结果表明:中性平衡法分析结果与有限元法的结果一致;按规范规定,摇摆柱的计算长度系数为1,但分析结果都大于1;对刚架柱,各规范或规程的计算结果不仅相差较大,而且与中性平衡法的分析结果相差也比较大.说明规范方法并不适用计算铰接门式刚架的稳定性,对于此类刚架应该通过稳定分析获得刚架柱计算长度系数.

| Abstract: | Five gabled frames with hinges are analyzed by the equilibrium method and the effective length factors of coulumns are determined by solving stability equations,theoretical analysis and codes for design or technical specifications.The calculation results show that the results of the equilibrium method and the finite element method are consistent;the effective length factors of leaning columns are equla to one by codes for design or technical specifications,but greater than one by the equilibrium method;for ... |
