| 摘 要： | 为了研究用钢筋混凝土摩擦耗能支撑对既有框架结构加固后的抗震性能,利用ETABS软件模拟既有框架结构加固前和加固后的模型。对比了两个模型的层间位移角、剪重比以及内力变化。通过研究表明:增设耗能支撑的加固措施,不仅能有效地改善既有框架结构的抗侧刚度,而且在罕遇地震作用下还能提供很好的耗能减震性能,从而使既有框架结构加固后具有足够的抗震安全储备实现其抗震设防目标。

| Abstract: | By adding RC friction energy dissipation brace,research the seismic performance of the existing frame structure,ETABS software was used of building model,and in the same of earthquake,analysis and comparison angle of floor displacement,shear weight ratio and the changes of internal forces.The results show that adding RC friction energy dissipation brace,not only improving lateral stiffness of the existing frame structure,and providing good energy dissipation properties under earthquakes.The existing frame structure has enough seismic safety reserve to realize the goal of seismic fortification. |
