Finite Element Analysis on Dynamic Behavior of Gangue Concrete-Filled Circular Steel Tube Beam
The dynamic behavior of gangue concrete filled circular steel tube beam with different steel ratio under the cyclic loads are analyzed and studied based on finite element analysis software ABAQUS. Through reasonable modeling established, parameter set, an effective grid meshed, the hysteresis curve of gangue concrete filled circular steel tube beam under low-cycle reversed loading is given, and verified compared with the experimental results. The comparison shows that the simulated hysteretic curve gives results in close agreement with the experimental results. The simulated curve shows that there has the characteristic of spindle-shaped and no significant decline in stiffness of the hysteresis curve. And the fatness of hysteresis loop is better.
