| 摘 要： | 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。

| Abstract: | Based on engineering practices,locally concave slabs with double-side sinking plate were studied by FEM.The comparison of mechanical behavior between locally concave slab and flat plate was carried out.Analysis result shows that the force of short side direction reduced significantly,while the force of long side direction increased,and material stress decreased except the location of conjunction.Based on above findings,some advice for design was presented. |
