摘要

科兴中维某框架结构因工艺调整、抗震设防类别提高,采用增设黏滞阻尼器的消能减震加固方式.本文通过建立弹塑性模型进行大震弹塑性分析,结果表明本结构减震加固后,黏滞阻尼器起到了良好的减震耗能作用,结构顶点位移、层间位移角、基底剪力等关键指标均满足大震要求;地震能量主要由黏滞阻尼器及框架梁消耗,框架柱基本不参与耗能;减震加固后框架梁满足性能水准要求,框架柱包钢加固后满足性能水准要求.

Abstract

Due to the process adjustment and fortification category improvement,a frame structure of Sinvoac adopts the shock-absorption reinforcement method with the addition of viscous dampers.In this paper,the elastoplastic analysis of rare earthquakes is carried out by constructing an elastoplastic model.The results show that after adding dampers for shock-absorbing reinforcement of the structure,the key indicators such as structural apex displacement,interstory displacement angle,and base shear force all meet the requirements of rare earthquakes;the seismic energy is mainly dissipated by dampers and frame beams,and frame columns are basically not involved in energy consumption;after shock-absorption reinforcement,the frame beams meet the performance level requirements,and the frame column meets the performance level requirements after reinforced by the outer steel.
