摘要
基于结构附加阻尼及附加刚度变化对地震响应的影响规律,推导了黏滞阻尼器(VFD)与钢框架-钢板剪力墙新型组合减震结构位移降低率和剪力降低率的计算式,绘制出了新型组合减震结构的减震性能曲线,给出了基于性能的组合减震设计步骤,并以1栋高烈度区实际工程为例对该方法进行了验证。结果表明,当结构位移降低率和剪力降低率确定时,结构存在减震性能点,基于性能设计可使新型组合减震结构对位移和剪力均取得较好的控制效果,能明显提高高烈度区钢框架-钢板剪力墙结构的抗震性能。
Based on the effects of changes of additional structural damping and additional stiffness on the seismic response, this paper deduced the design formulas of the reduction rates of displacement and the shearing force for the damping structure integrated with viscous fluid damper(VFD) and steel frame-steel shear plate wall.The curve of damping performance of the integrated damping structure was drawn, and the procedures of the integrated damping design was given based on the performance, which was verified by a concrete project in the high intensity region.Results show that when the reduction rates of displacement and the shearing force are confirmed, damping performance points exist in the structure, and performance-based design can have better control for the novel integrated damping structure on displacement and the shearing force as well as improve the damping performance of the steel frame-steel shear plate wall in the high intensity region.
