采用有限元方法对实际工程中存在的双侧降板型凹槽楼板进行了参数分析,比较了其与普通平板在内力分配特性和材料应力大小等方面的差异,发现此种楼板短边方向的受力有明显减小,而长边方向的受力有所增加,除顶板与降板连接部位外,材料应力均有大幅度的降低,结合以上特性给出了相应的设计建议。 The finite element method is used to analyze the parameters of the double-sided decking grooved floor in the actual project. The differences between the two-sided decking grooved floor slab and the common slab in terms of the internal force distribution and the material stress are compared. It is found that the short-side direction of the slab The force is obviously reduced, while the stress in the long-side direction is increased. Except for the connecting part between the top plate and the down plate, the material stress is greatly reduced, and the corresponding design suggestions are given according to the above characteristics.
