【摘要】 使用Sap2000软件对1栋9层钢筋混凝土人字形斜撑框架结构进行静力非线性分析和抗震性能评价。通过对普通混凝土斜支撑框架结构与在支撑中增设阻尼器的斜支撑框架结构进行比较表明:增设阻尼器后,结构在地震作用下,位移以及转角都有所减少,刚度和承载力大幅提高。更多还原

【Abstract】 Static nonlinear analysis and anti-seismic performance evaluation was performed on 9floors reinforced concrete herringbone braced frame structure by using software SAP2000.By comparision of the ordinary concrete inclined support frame structure and the inclined support frame structure that adding dampers,the result shows that the displacements and displacement angles of structure are much smaller under the action of earthquake after adding dampers,and its stiffness and bearing capacities are improved greatly.更多还原
