摘要
文章就一工程实例对人防地下室常用肋梁楼盖体系进行了分析,就柱网的合理布局和边跨的合理设计问题进行了探讨,并对整浇梁板共同工作问题进行了初步的考虑。结果表明,在相同设计条件下,合理的楼盖体系的选择应根据抗力级别确定;柱网宜设计成矩形,正交跨长比取0.65～0.7最合适;边跨取0.8～0.85倍内跨更合理;设计时应考虑整体现浇梁板共同作用的特性和原理,将现浇板作为框架梁的翼缘,共同参与受力分析。
Based on an actual project,the conventional girt strip roof system of civil air defence basement was analysed;the proper redistribution of column mesh and rational design of side span was discussed yet in the paper;and the cooperation effect of integral pouring beam-slab was considered initially.It can conclude that rational design of roof system is up to resisting class in the same design conditions;rectangle is fit for column mesh,the best ratio of orthogonal span is 0.65~0.7;the best length of side span is 0.8~0.85 times the length of interior span;the cooperation character of integral pouring beam-slab should be considered when we design.We should put slab as the flange of frame beam,engaging in stress analysis together.
