Performance simulation analysis and comparison of different shearing mild steel dampers

Abstract

Mild steel dampers are widely used in the field of engineering structures energy dissipation and seismic reduction because of its advantages such as easy manufacturing, low cost and easy installation and replacement. In order to analyse and compare the performance of the different mild steel dampers, eight different shape shearing mild steel dampers are designed in this paper, and the simulation analysis is conducted using Finite Element Method (FEM) of ABAQUS/Standard. And the bearing capacity, initial stiffness and energy dissipation capacity of the different shearing mild stell dampers are compared according to the simulation results. The analysis and comparison results show that the performance of shearing mild steel damper is greatly affected by its shape. Therefore, the different shearing mild steel dampers should be selected reasonably according to the engineering requirements.
