摘要
采用有限元方法研究有梁双向空心板的受力性能,尤其是在两个方向的受力性能的异同,为研究有梁双向空心板的刚度、变形和承载力提供科学依据。对于有梁双向空心板弹性阶段的受力性能分析,采用了等效刚度板法(拟板法),拟板法的思路是将双向空心板等效为一均质的具有正交各向异性特征的实心板(拟板),在此基础上对拟板进行分析。
To provide a scientific basis for the calculation of stiffness,deflection and ultimate load bearing capacity, finite element analysis method is used and the study is especially focused on the comparison of mechanical characteristics in two different directions.Using the equivalent stiffness method the structure is converted to a kind of orthotropic shell element.
