摘要:
对目前研究尚少的开洞无梁楼板极限承载力的计算问题进行了分析探讨,重点研究了在竖向均布荷载作用下结构形式和开洞形式较规整楼板的内力计算方法.先将开洞无梁楼板等效成与之抗弯刚度相等的等截面连续梁,计算了连续梁的总静力弯矩,再采用屈服线理论对一块开洞方板的极限承载力进行分析,最后对计算结果进行综合,得出了各板带对应于不同开洞比的弯矩值,以便实际工程设计中应用参考.
Abstract:
A simplified analysis of the calculation method of ultimate resistance of flat slabs with openings is presented there have been few studies on this topic. The emphasis is the regular flat slabs with openings in the center bearing the lateral uniform load. The static bending moment is calculated after making the flat slabs with openings equivalent to a continuous beam based on the same bending capacity. Then yield line theory is used to get the ultimate resistance of a slab with opening. A simplified calculation formula of each slab belt is given after detailed deduction. This formula can be used directly in practical engineering design.
