摘要
通过分析剪力墙结构刚度和地震作用之间的关系,提出了在某一设防烈度下地震区剪力墙结构的刚度优化模型,利用结构优化设计之一--一维搜索法对剪力墙结构进行优化设计,以地震作用最小为目标,以抗侧刚度为变量,以结构水平位移、层间位移角、强度、轴压比、构件几何尺寸等位约束条件,用MATLAB语言编制了在水平荷载作用下的计算程序,通过实例证明该方法是有效的。
The article established the stiffness optimization model of shear wall structure in the earthquake zone under the fortification intensity by analyzing the relationship of the stiffness and seismic shear-wall structures,and used an one-dimensional search method-one of the structural optimization design for the shear wall structure optimized design.Take the minimization earthquake action as the goal,the lateral stiffness as the variable and the structure horizontal displacement,story drift angle,intensity,and axial compression ratio,component geometry as the constraints,made a calculation program in MATLAB under the horizontal load.An example proved that the method is effective.
