Hysteresis Analysis of RC Columns Based on Fiber Cross-Section Model

Abstract:

Article Preview

The seismic performance of reinforced concrete(RC) columns is one of the controlling factors of the shock resistance for RC frame structures and bridges under seismic loads. Due to the complicated material behavior and complex external force during the earthquake, an accurate simulation of the mechanical performance under seismic loads demands more precisions for the hysteresis constitutive laws of materials. In this paper, based on the fiber cross-section model, adopting revised Kent-Park model for concrete and Legeron model for steel reinforcement, programming the UMAT material subroutine, FEM software ABAQUS is used to simulate a RC column mentioned in a research. It’s results are found agreed well with the test results.
