降板对现浇板受力性能的影响

The Influence of Descending Plate Impacting on Monolithic Slab

现浇板降板是工程中的常见的构造。为研究降板后楼板的受力性能,利用sap2000,建立6个不同降板高度的模型。对比各模型现浇板在不同方向上的内力分布状态,得到现浇板随着降板高度的变化引起的楼板内力分布变化的规律。对比不同模型降板交界处的内力状态,得到不同降板高度下的降板交界处构造的内力变化规律,并基此提出设计建议。

Descending plate is common structure in structural engineering. To study the force distribution of descending plate,6 finite models of different descending depth are built with Sap2000. Comparision of force distribution situations of different models are made to analysis how the descending depth impact on the force distribution of the slab. Comparison of force distribution situations of different models at the descending boundary is also made to analysis how the descending depth impact on the force distribution of the boundary. Some advices for design are proposed.
