【摘要】：地下室楼板不连续包括楼板大开洞、错层、设置施工后浇带等三种情况,采用有限元计算模型,详细分析了楼板不连续对构件内力的影响。通过分析得出如下结论:楼板大开洞且洞口长度与洞边距之比L/S大于1、楼板错层、设置后浇带时,应采用可以考虑楼板变形的有限元软件计算构件内力;楼板错层、纵横设置多道后浇带的中间区域,构件内力较大开洞时增大更多,设计更应引起足够重视。
[Abstract]:The discontinuity of basement floor includes three kinds of cases, such as large opening of floor, staggered floor and setting up construction post-pouring belt. The finite element calculation model is adopted. The influence of floor discontinuity on the internal force of the member is analyzed in detail. The following conclusions are drawn: the ratio of the opening length of the floor to the margin of the hole is greater than 1, and the floor is staggered, when the post-pouring zone is set. The finite element software should be used to calculate the internal force of the member. If the floor is staggered and the middle area of the multi-channel post-pouring zone is arranged vertically and horizontally, the internal force of the member increases more when the opening is larger, and the design should be paid more attention to.
