线性与非线性黏滞阻尼支撑减震效果的比较
|
摘要
黏滞阻尼器的速度指数取值制约着阻尼支撑减震效果,需确定合理的速度指数取值范围.从工程设计应用出发,按2种思路比较房屋在分别设置线性与非线性黏滞阻尼支撑后产生的结构响应、减震效果、柱轴力、经济性和安全性.研究结果表明:非线性黏滞阻尼支撑在小震下较为经济有效,在大震下抗震安全度较高且方便相关支撑与连接设计的结论.
The velocity index of the damper may result in different seismic-reduced effects,so it was necessary to confirm the proper range of the velocity index.The seismic-reduced effect,structural response,column force,cost and safety of structure under the control of linear and nonlinear viscous damper bracings were compared.The results showed that nonlinear viscous damper bracings were more effective and economical under the common earthquake intensity scale.Thus it was safer and advantageous for the design on the strong earthquake intensity scale.
