摘要
以典型规则框架结构为研究对象，针对框架结构在多遇水平地震作用下仍处于弹性工作阶段这一基本事实，利用结构优化设计原理及抗震设计基本理论，时框架结构提出了弹性工作阶段以顶点侧移为控制目标的结构优化模式，确定了优化目标函数，最终给出了典型规则R．C框架结构在多遇水平地震作用下梁、柱截面尺寸的计算公式及梁、柱最佳刚度比的表格形式。
This paper focuses on the typical regular R. C frame structure. Considering the fact thatframe structure still works at its elastic stage under frequent horizontal seismic action, and based on theprinciple of structure optimum design and the theory of anti - seismic design, a structure optimum modewhose control objective is apex lateral displacement is presental for frame structure.And an optimunobjective function is consequently determined . Finally this paper gives the calculation formula for sections'dimension of beams and columns of typical regular R. C frame structure. And the form of beamsnd columns optimum rigidity ratio is presented for engineers' reference.
