| 摘 要： | 《钢结构设计规范》(GB 5 0 0 17-送审稿 )关于强支撑框架判别式 ,在其条文说明中没有就该判别式从理论公式到规范实际应用公式的简化、修改作出说明。为此 ,讨论强支撑框架判别式的合理性。总结了在工程设计中 ,无侧移框架判别式或强支撑框架判别式应用于仅部分层间有斜撑的框架及错层框架稳定性计算时所遇到的问题

| Abstract: | There are no explanations of the simplifying and revising the discriminant from its theoretical formula to a practical one in the code,which is used for a strongly braced frame in “Code for Design of Steel Structures”(GB 50017).Therefore,the rationality of the discriminant for the strongly braced frames is discussed.The problems of calculating the stabilities of the frames and the staggered frames with skew bracing systems only on partial floors,using the discriminant of a non sway frame or that of a strongly braced frame are also summarized during engineering designs. |
