摘要
某工程玻璃幕墙钢框架体型复杂,以斜立柱、斜梁和斜撑构成一个稳定性良好的空间框架结构。在该结构中,斜立柱和梁等关键构件的计算长度系数难以套用现行规范来确定。通过屈曲分析,研究斜撑对斜立柱和梁的稳定性的影响,并采用分片加载的方法最终确定各个构件的计算长度系数。
This glass curtain steel frame shape is complicated which is well stability and interactive space system with the declining columns,declining beams and braces.However,the effective length factor of declining columns and beams is decided difficultly.By the buckling analysis,the effect of the braces on the declining columns and beams is studied and the effective length factor of every member by applying local load in final is decided.
