【摘要】 针对网架结构特点,提出采用粘滞流体阻尼器作为冗余杆件和粘弹性阻尼器替换原杆件两种方法对网架结构进行消能减震。以一正放四角锥网架为模型,对其采用消能减震技术前后结构地震响应进行对比结果表明,上述两种方法均可以有效减小网架结构的地震响应。同时,对阻尼器布置位置变化对减震效果的影响进行分析比较。更多还原

【Abstract】 Based on the structure property of space truss,it is suggested to use vibration energy dissipation method for reducing earthquake response.The detailed precept includes the following two different ways: using fluid viscous damper as additional elements or using viscoelastic damper to replace the elements.In a case of a pyramid space truss model seismic response is compared before and after seismic mitigation.Calculation results show the methods mentioned above are effective.Furthermore the influence of change in damper locations on the vibration reduction is investigated.更多还原
