A Discussion about the Improvement of Finite Element Analysis Units of Castellated Beam
Castellated beam is a kind of holed web plate structural beam, since it has many advantages: savings in steel, light self-weight, resists bending and easy to deploy, the application of this structural beam becomes more and more widely. Due to its weakened web plate, castellated beam would be affected by shear effects greatly. The deformation of components increased under the affects of external loads. Therefore, in order to improve the accuracy of finite element analysis model, by consideration of the shearing effects and the bending stiffness affected under opened structure, this issue made improvement based on the theory of curved beams. By compare the results from this issue and the result from the analytical model of shell elements; we verify the feasibility of this method.
