摘要
以某采用软钢阻尼器的框架结构设计为例,介绍了软钢阻尼体系的等值线性计算方法及改进,包括等值柱的计算方法、地震波的选取、混凝土斜撑支座和剪力墙支座的选取、局部耗能元件采用附加阻尼比的形式推广到整体结构时的有效性、阻尼比迭代计算时荷载工况的选取、迭代刚度的选取及阻尼器周围框架的设计。得到的一些结论或建议可供类似项目参考。
In this paper, the equivalent linear calculation method for hysteretic damping system was introduced, taking the design of a frame with mild steel dampers as an example. The equivalent column calculation method, earthquake wave selection, concrete bracing support and shear wall bearing selection, the influence of the additional damping ratio on the entire structural system instead of local energy dissipation elements, loading cases for iterative calculation of damping ratio, and iteration stiffness selection and the frame bearing damper design, were discussed in this manuscript. Conclusions and suggestions were drawn from the analyses.
