【摘要】 以新疆某12层钢筋混凝土框架剪力墙结构为例,采用消能减震技术进行加固改造,并进行了弹塑性动力时程分析。结果表明:首层剪力明显减小,X、Y方向层间位移均有不同程度的减小,因此,采用黏滞流体阻尼器使得该结构的抗震性能得到提升,满足现有抗震规范的要求。更多还原

【Abstract】 A twelve layers reinforced concrete frame-shear wall structure in Xinjiang is taken as an example. The building is reinforced and reconstruction by use of vibration energy dissipation technology and its dynamic time history analysis is conducted. The results show that shear force in the first layer decreases,and the damping rates of layer displacement in X and Y directions decrease in different degree. Therefore the seismic performance of the structure is improved by using viscous fluid dampers,which could meet the requirements of the current seismic code.更多还原
