摘要
文章研究用于控制高层钢结构建筑地震反应的粘弹性阻尼器 (VED)设计方法。首先建立支撑杆的单元复刚度矩阵 ,求解结构等效阻尼比 ,在此基础上 ,进行阻尼器参数设计 ,提出了适合于一般钢结构的设计方法和适合于剪切型钢结构的简便方法。然后以一十二层高层钢结构为例 ,验证了阻尼器对高层钢结构建筑地震反应控制的良好效果
A earthquake resistant design method of steel tall buildings installed with viscoelastic dampers(VED) is studied. The elemental complex stiffness matrix of VED brace is established firstly. The effective damping ratio of steel tall buildings installed with VED is solved. Then, the parametrical design of VED is carried out. A 12-storey building is adopted to confirm the efficiency of the earthquake resistant of steel tall buildings installed with VED.
