| 摘 要： | 以现行建筑结构荷载规范为基础,系统地介绍了荷载效应组合的基本规则,讨论了承载能力极限状态下的荷载效应组合设计值的计算方法.通过理论推导,给出了得到荷载效应最不利组合的简化判别方法和条件.结果表明,荷载效应最不利组合可以通过永久荷载标准值与主导可变荷载标准值的比值来判别.对于给定的荷载条件,永久荷载标准值与主导可变荷载标准值的比值达到某一数值时,最不利荷载效应组合由永久荷载效应的组合控制,否则由可变荷载效应的组合控制.

| Abstract: | Based on the current load code for the design of building structures,the basic rules of load combinations are systematically introduced,and the calculation method for load effect design values under the carrying capacity limit is discussed.The conditions and simplified method for judging the most disadvantageous load effect combinations are obtained by means of theoretical derivation.The results show that the most disadvantageous load effect combination could be distinguished by the ratios of the nominal va... |
