近年来国内外对土建结构设计的优化进行了大量工作。优化的对象涉及结构工程的各个方面。本文试图综述各国在土建结构设计中运用优化技术的概况,类如梁、懔条、框排架、桥梁、桅杆以及建筑体系等,着重于所采用的数学模型与经济效果。评述仅限于实际应用的范围,并不包括有关的全部文献,本文正讨论了在建立优化数学模型时土建结构在目标函数、约束条件以及设计变量上的一些特点和问题。
In recent years, a great deal of work has been done at home and abroad to optimize the design of civil structures. The object of optimization involves all aspects of structural engineering. This article attempts to review the overview of various countries in the use of optimization techniques in the design of civil structures, such as beams, purlins, framed frames, bridges, masts, and building systems, focusing on the mathematical model used and economic effects. The review is limited to the scope of practical application and does not include all relevant literature. This article discusses some characteristics and problems of the civil structure in the objective function, constraints, and design variables when establishing an optimized mathematical model.
