前言在力学的发展过程中,结构最优设计的想法由来已久,但只有在最近十几年,当结构计算理论,数学方法和计算工具逐步解决以后才有可能得到迅速的发展。开始时研究限于结构静力的最优设计,后来发展到结构动力的最优设计,而抗震结构的最优设计是在七十年代出现的最新的学科分支。木文的目的是想简要地介绍抗震结构最优设计的理 Introduction In the development of mechanics, the idea of ​​structural optimal design has a long history, but only in the last decade or so, it is possible to get rapid development after structural calculation theory, mathematical methods and calculation tools are gradually solved. At the beginning, the study was limited to the optimal design of structural statics and later to the optimal design of structural dynamics. The optimal design of the seismic structure was the latest branch of the discipline that appeared in the 1970s. The purpose of Muwen is to briefly introduce the optimal design of seismic structures.
