Some Problems on Applying Symmetrization in Finite Element Analysis of the Slab on Elastic Solid Foundations
-
摘要: 本文解决了用有限元法分析弹性固体地基板时,在任意荷载作用下只需取1/4板进行计算的方法问题。Abstract: In this paper, a method of forming stiffness matrices for a quarter of slab and subgrade has been developed, which may be used for analysing arbitrarily loaded slabs on elastic solid foundation with finite element method.
