|
摘要
根据钢筋混凝土框架及抗震墙的模型试验数据 ,确定了各种变形阶段框架及抗震墙的割线刚度 ;并分析了多高层建筑结构侧移的成分 ,以及引起震害的侧移 ,将不同变形阶段框架及抗震墙的割线刚度、目标位移的控制值与引起震害的侧移值相联系 ,按割线刚度、采用矩阵位移法对高层框架 -抗震墙结构进行分析。从而得到遭遇本地区多遇地震、设防烈度地震及罕遇地震时 ,结构的弹塑性变形 ,框架、抗震墙及连梁的刚度退化程度 ,以及水平地震作用在框架和抗震墙之间分配规律的变化
The secant stiffnesseses of frames and anti-earthquate walls at different deformation stages are determined from experimental data. The composition of lateral deformation of RC high-rise structures, as well as the lateral deformation caused by seismic damage,are carefully investigated.Correlating the secant stiffnesses of frames and aseismic walls at different deformation stages,with the target deformation and the lateral deformation caused by seismic damage, the seismic responses of structures are forecasted for various seismic intensities, so that the behavior of the structures is understood, and the precise values of the maximum seismic forces acting on the frames and the aseismic walls are obtained. An example is provided to demonstrate the proposed method.
