Finite Element Analysis of Mechanical Behavior for Prestressed Concrete Wide-flat Beam Frame Exterior Joints

In order to analyze the arrangement of prestressed reinforcement to node stress performance, this paper uses the ANSYS software to simulate the test process of prestressed concrete wide-flat beam frame exterior joint in elastic stage, analyze their stress performance from macroscopy, and compare with ordinary reinforced concrete specimens.With prestressed tendons all wearing column, partially wearing column and not wearing column respectively as the parameters for simulation, there are small error between the simulation results and the corresponding experimental results, which coincides with experimental results well.
