网格梁楼面等效荷载的拟板法

Quasi-plate method for equivalent load on two-way rib slab

在忽略扭矩的情况下,对经典薄板理论中的重三角级数系数算法做了改进,以适应于混凝土网格梁体系。这种改进的算法谓之"拟板法"。通过计算对比,验证了拟板法的适用性。针对在一组移动荷载下的网格梁体系的等效荷载,提出了等效荷载的确定方法。

To satisfy the analysis for two-way rib slab,the calculation formula for coefficients of double trigonometric series was improved by ignoring torsion in elastic plate,which called quasi-plate method. Computation results were made in contrast with finite element methods to illustrate it' s serviceability. For a set of loads moving on two-way rib slab,the procedure of equivalent load determination was provided.
