框架-抗震墙结构抗震墙抗弯刚度的优化研究

框架-抗震墙结构中抗震墙设置数量的多少是框架-抗震墙结构体系是否安全、经济、合理的关键。抗震墙设置过少，结构不安全；抗震墙过多，地震作用加大而不经济，不能充分发挥框架-抗震墙结构的结构优越性。根据框架-抗震墙结构连续化原理，求得结构的基本周期、顶点位移和最大层间位移角，建立优化数学模型，可准确地求出框架-抗震墙结构所需最优抗震墙的抗弯刚度值。同时求得最大层间位移角的具体位置，并据此求出7、8、9烈度区不同高度框架-抗震墙结构层面积为1000m^2时所需的抗震墙抗弯刚度值，可供设计参考。

Study on optimum bending rigidity of seismic wall in frame-shear wall structure

Quantity of earthquake resisting wall setup in frame-shear wall structure is key whether or not structure is safety,economy and reasonable.If the quantity is over little,structure is unsafe; if the quantity is over abundance,the superiority of frame-shear wall structure is not sufficiency given out and earthquake action increase.Based on the principle of continuum on frame-shear wall,the basic period,the apex displacement and the most story drift angle are obtained,an optimum method is presented.The furthest excellent bending rigidity of seismic wall of frame-shear wall structure will be worked out well and truly.The place of the most story drift angle is sought in the article.Through the method,it is obtained that the furthest excellent bending rigidity of seismic wall of various height of frame-shear wall structure with 1 000 m2 area per layer on 7,8,9 intensity section,which can give reface to design.
