Nonlinear finite element analysis of new type composite beam-slab system with PBL shear connectors

Based on the specific demands of emergency repair on civil project facilities, the new type composite beam-slab system with PBL shear connectors was put forward. The results of the experiment indicate that the new type structure system has many advantages, such as high bearing capability, well durability and simple construction etc. In this paper, the whole course and nonlinear numerical modeling about those composite beams were performed by commercial FEM program ANSYS and private synthetic iterative program, contrast analyses were executed. By analyzed with FEM, the experimental results could be verified.
