利用有限元分析软件ANSYS,结合优化设计方法,以某6层框架结构为例,以其柱网尺寸和梁、柱截面尺寸为设计变量,单位建筑面积上的混凝土用量(造价)最低为目标,在满足我国现行规范的强度、位移及构造要求的前提下,对其进行多遇地震作用下的结构优化设计,得出最优解。 Taking finite element analysis software ANSYS and optimization design method as an example, taking a 6-layer frame structure as an example, taking the column net size and the beam and column cross-sectional dimensions as design variables and the concrete dosage (cost) per unit of floor area as the minimum, Under the premise of meeting the strength, displacement and construction requirements of the current norms in our country, the optimized structure of the structure under the action of frequent earthquakes is obtained and the optimal solution is obtained.
