Square Steel Pipe Regeneration Block Party of a Concrete Column Nonlinear Finite Element Analysis

Abstract:

By testing the Axial compression performance of the Block of concrete short columns regenerated by No rib and steel ribbed thin-walled square and simulating the finite element program ANSYS calculation ,we are going to reveal the square steel tube regeneration block of mixed component axial compressive deformation and failure mode ,and analyze the longitudinal force and the strain relationship of the longitudinal direction and the horizontal direction as well as the effect on forcing performance and failure mode of specimen played by the combined concrete force of fresh concrete. The results showed that the main failure mode of specimen is crushed drum-type damage. In the elastic state, all the strain growth in the middle section and the corner is self and growth of longitudinal strain of the two is relatively consistent. On damaging stage, the specimen without ribs is softened, while the specimen with ribs shows a feature of stiffening. The results of finite element analysis fit the test results well.
