Abstract: A new Energy dissipation bracket is proposed, which is simple in construction and easy to be replaced. Quasi-static tests were conducted. The mechanical and fatigue properties of the bracket with different ratios of width and thickness were studied, and the influence of the width-thickness ratio of the energy dissipation plate on the mechanical properties of the bracket was analyzed. The test shows that the energy dissipation bracket has good hysteretic property and stable energy dissipation property. In a certain range, the larger the width-thickness ratio of the energy dissipation plate, the better the ductility and energy dissipation capacity of the energy dissipation bracket.
