安装速度相关型消能器结构直接基于位移可靠度的抗震设计方法
|
摘要
考察了大震作用下安装速度相关型消能器结构的薄弱层层间位移可靠度指标增大系数与原无控结构薄弱层层间位移可靠度指标、第一振型附加阻尼比和粘弹性材料损耗因子之间的定量关系,提出了该类有控结构直接基于位移可靠度的抗震设计步骤。
The relationship between the interstorey drift reliability augment coefficient for the weak storey of the structure with velocity-dependent dampers and the interstorey drift reliability for the weak storey of the primary un- controlled structure,the additional damping ratio of the first mode and the loss factor of viscoelastic material is in- vestigated for major earthquake.Combining with the direct displacement reliability-based seismic design method of uncontrolled structures,the direct displacement reliability-based seismic design procedure is proposed for structures with velocity-dependent dampers.
