【摘要】 利用建筑物钢筋混凝土墙体作为承受竖向荷载、抵抗水平荷载的结构,称为剪力墙结构体系。剪力墙结构的优点可概括为:刚度大,空间整体性好,结构顶点水平位移和层间位移通常较小,能够满足抗震变形要求。因此,剪力墙的抗震性能在剪力墙结构及框架—剪力墙结构中发挥着重要的作用,剪力墙的数量会影响框架—剪力墙结构的刚度。本文通过位移模式得到了刚度特征值—反弯点相对高度曲线。更多还原

【Abstract】 Use of R/C shear wall as a vertical load to bear against the horizontal load of the structure,known as the shear wall structure system.The advantages of shear wall structure:large stiffness,good space overall,smaller vertex structure of horizontal displacement and story drift,which are able to meet the requirements of anti-seismic deformation.Therefore,seismic performance of shear wall plays an important role on the shear wall structure and framework-wall structure.The number of shear wall impact structural stiffness.This article has been through the displacement mode eigenvalue stiffness-a relatively high point of anti-bending curve.更多还原
