Abstract
There are a lot of previous studies which have introduced the Huber's hypothesis on the torsional stiffness for the orthotropic plate analysis. However, research of the general slab with arbitrary bending and torsional stiffness has seldom been reported. In this paper, authors carry out three-dimensional finite element analysis in order to obtain the bending and torsional stiffness of symmetrical circular voided slab as an example. The results prove that Huber's hypothesis is not always accurate. Then, we acquire the series solution of the orthotropic plates with arbitrary torsional stiffness under uniform load. The analysis is conducted under 3 cases boundary condition.
