Numerical simulation of unbonded prestressed concrete beams using improved applied element method

Applied Element Method (AEM) is a relatively new method for structural analysis developed by Kimiro Meguro and Hatem Tagel Din in 1997. It can capture the behavior of structure up to failure. In this method, structure is discretized into rigid elements connected by springs. The stiffness matrix of the structure consists of that of springs only. Here, the method is used to find out the failure load and predict the crack propagation. Two methods are available to determine the crack pattern namely unloading-reloading method and residual force method. These approaches are used to maintain equilibrium during the process of cracking. In this paper, these methods are discussed and they are used for the analysis of plain concrete beams with different support conditions.

Roof Structure

Combined with the roof of a warehouse the arched shell roof structure is select, simulation Numerical simulation is carried out for the arched shell roof structure system by the ANSYS finite element method, the deformation and stress are obtained which meet the specification requirements. So it is reasonable to select the thin vaulted roof. Finally, the arrangements of the two prestressing tendons of prestressed concrete beams in the framework and the matter which needs to be paid attention to during designing are given, and these can provide reference for similar finite element solution and design of the structural system.
