摘　　要：科兴中维某框架-抗震墙结构因工艺调整,抗震设防类别提高,采取隔震的方式进行抗震加固。本文通过建立弹塑性模型进行大震弹塑性分析,结果表明本结构隔震加固后,隔震层以上楼层,两方向层间位移角、抗倾覆、剪重比等关键指标均满足大震要求;隔震支座消耗总能量接近地震输入能量的2/3;隔震支座抗拉、抗压和位移均满足大震下规范要求;隔震层以上构件并未出现较严重的损坏;隔震层以下支撑隔震支座的框架柱经加固后,满足大震承载力要求。Due to process adjustment,a frame-seismic wall structure of Sinvoac changed its fortification category and adopted seismic isolation for reinforcement.In this paper,the elastoplastic analysis of rare earthquakes is carried out by constructing an elastoplastic model.The results show that after the seismic isolation and reinforcement of the structure,the key indicators such as the story drift angle,anti-overturning resistance,and shear-weight ratio in both directions of the floors above the seismic isolation layer can meet the requirements of rare earthquakes.The total energy consumed by the isolation bearing is close to 2/3 of the seismic input energy;the tensile strength,compressive strength and displacement of the seismic isolation bearing all meet the requirements of the code under rare earthquakes;the components above the seismic isolation layer have not been damaged severely;the frame columns supporting the seismic isolation bearing below the seismic isolation layer were reinforced.Finally,it meets the seismic bearing capacity requirements of rare earthquakes.
