| Abstract: | According to the practical requirements of engineering structures, some new types of viscoelastic energy dissipation braces are proposed and their force bearing properties are studied; the calculation formula of horizontal control force of the energy dissipation brace is also given. The demands of strength for steel bars are presented. The effects of tension and compression stiffness for steel bars on the loss factor and shear stiffness of viscoelastic damper are analyzed. Considering the effect of stiffness of steel bars, a calculation formula of horizontal control force of the energy dissipation brace is proposed. The paper points out that the tension and compression stiffness of the steel bar is important to the effect of energy dissipation. Based on feasibility of engineering, the demands of stiffness for steel bars are presented at last. |
