使用阻尼器加固后建筑物地震响应研究

摘要

以某实际加固工程为工程背景，利用 SAP2000有限元软件，分析了建筑物加固前和加固后地震响应情况，通过对比楼层平均位移、层间剪切变形、建筑物基底剪力弯矩后，得出了阻尼器对建筑物的影响规律，研究表明，使用阻尼器加固后，在地震作用下建筑物能大幅减少楼层位移以及层间剪切变形，同时也能大幅减少建筑物的内力。%Taking a practical reinforcement project as engineering background. By finite element software SAP2000,analyzes building reinforce-ment before and after the earthquake response situation,after a mean displacement floor,interlaminar shear deformation,after building the base shear moment contrast can come damper on the influence of the building. Studies have shown that the use of the damper reinforcement after the earthquake the building can significantly reduce the displacement between floors and interlaminar shear deformation,but also can significantly re-duce the internal forces building.
