摘要:
针对工程中实际需要,提出一些新型的黏弹性消能支撑型式,研究了它们的受力特点,并给出了消能支撑水平控制力的表达式; 提出了消能支撑设计中钢杆应满足的承载力要求; 同时分析了支撑中钢杆拉压刚度对黏弹性阻尼器损耗因子和抗剪刚度的影响,并在此基础上给出了考虑钢杆拉压刚度影响的消能支撑水平控制力表达式; 最后指出钢杆的拉压刚度对减震效果影响较大,在考虑工程可行性的基础上给出了钢杆应满足的刚度要求.
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.
