| 摘 要： | 根据现浇混凝土空心板正交各向异性主刚度之间的关系D3=√D1D2,将正交各向异性板等效为各向同性板,通过分析得到现浇空心混凝土无梁楼盖的挠度和内力计算方法:等效各向同性板任意点的挠度就是原正交各向异性板对应点的挠度;均布荷载下的内力分配与相同尺寸的各向同性板无梁楼盖相同,可以按经验系数法提供的参数进行计算.

| Abstract: | Based on the orthotropic character of D 3= D 1D 2 of cast-in-situ concrete hollowed flat plate,the original orthotropic flat plate equivalents to an isotropic flat plate.Results obtained through analysis: the deflection of the equivalent isotropic plate is same to the deflection of the original orthotropic plate at the correspondent points;the distribution of the bending moment of the hollowed flat plate is same to the isotropic flat plate with the same size. |

| Keywords: | hollow slab flat plate orthotropic plate equivalent |
