Abstract:
In order to study the seismic performance of the flexural member with low yield point distributed damping element,and to compare the mechanical performance and the hysteretic energy dissipation performance of the distributed damping flexural member with the normal flexural member,a finite element analysis was carried out to a cantilever beam with distributed low yield point energy dissipation material based on the theory of shock absorption technology at component level in this paper.The finite element analysis model is established by ABAQUS software to simulate the energy consumption after the damping material yield due from the relative deformation of the contact surface between RC beam and damping layers.The deformation performance and hysteretic energy dissipation was summarized and compared with those ordinary cantilever beams.According to the results of the finite element analysis,it was found that the distributed low yield point energy dissipating material can obviously restrain the deformation of the concrete in the tensile zone of the flexural member,and the energy dissipation will be realized when the low yield point plate yield is yielded.Therefore,it can be considered that the distribution damping can improve the stress and hysteresis performance of the flexural members through reasonable design.After distribution damping,the damage of the component and the hysteretic energy dissipation performance is improved. © 2018, Editorial Department of Journal of SJZU.
