中高层异形柱框-剪结构的剪力墙抗侧刚度优化
|
摘要
综合考虑剪力墙剪切变形、异形框架柱轴向变形和连梁刚度对异形柱框架-剪力墙结构的抗侧刚度的影响,对抗震设防区的中高层钢筋混凝土异形柱框架-剪力墙结构体系住宅进行剪力墙抗侧刚度的优化,同时采用底部剪力法分析剪力墙抗侧刚度与水平地震作用的关系,考虑层间位移、刚重比、剪重比等约束条件建立优化数学模型,并结合新规范给出模型的数值解.算例结果表明本优化模型可行、有效.
The effects of the shear deformation of shear wall, the axial deformation of special-shaped column and the stiffness of binding beams on the lateral stiffness of RC. frame-shearwall structure with special-shaped columns are considered, the lateral stiffness of shear wall in mid-highrise residential buildings of RC. frame-shearwall structure are optimized. Using the bottom-shear method, the relation between lateral stiffness of shear wall and earthquake action are analysed, and a mathematical model is constructed with interstorey drift, the ratio of lateral stiffness to gravity, storey shear to gravity as constrained conditions, and the numerical solution is presented. An example shows the model was feasible and effective.
