FEM Analysis of Concrete Filled Square Steel Tubular Columns with Energy Dissipation Plate

Abstract:

In order to improve the seismic energy dissipation performance of concrete filled square steel tubular (CFST) columns, the structural measure about puting the additional energy dissipation plat at the bottom of the CFST columns where bears more stress, was proposed. Finite element anylsis of 10 CFST columns with different structural measure were performed under the same axial compression, selecting the thickness and height of the energy dissipation plate as parameters. On the basis of finite element anylasis, this paper, which obtained load-displacement curves of each finite element model, analyzed and compared the bearing capacity of each model. The results show that: comparing to the ordinary CFST columns, the columns with energy dissipation plat show better about bearing capacity and seismic performance, the height of the energy dissipation has a significant effect on bearing capacity but the thickness has less impact.
