折板基础的有限元分析及简化计算

Finite Element Analysis and Simplified Computing of Folded Plate Foundation

将作用于折板上的地反力换算成等效的均布荷载，根据构造措施和实际受力情况，可按周边固定的单元板进行计算．对折板基础进行有限元分析，并与弯矩分配法计算结果进行比较，说明有限元方法与弯矩分配法的计算结果基本吻合，同时能提供更详尽的数据，是分析折板基础的可靠方法．

The contract force applying the folded plate is translated into the distributed loading with the equiva- lent effect. According to structure and applying load, the folded plate is treated as the one with all fixed boundaries. The folded plate is analyzed with the finite element method. The results of FEA method almost coincide with the ones of moment distribution method and provide more elaborate information. Consequently, the FEA method is a reliable one analyzing folded plate foundation.
