摘要: 算法取代工程师的人工调试工作一直是一个比较热门的结构设计研究方向，但未大量应用于工程实际。主要介绍了实际工程中，利用结构设计行业内出现的新变量，如更高效的优化算法、编程能力在新一代结构设计从业人员中的普及、国内一线设计软件逐步开放程序控制接口等，针对不同工程实际问题采用不同算法进行设计的实际案例；并介绍了采用算法设计的优势，如在超高层设计中采用了响应面算法优化型钢用量，在大跨度天幕设计中采用模拟退火算法进行曲线找形，在桩基设计中通过对桩布置进行参数化快速设计更新。 通过这些案例笔者认为结构设计行业推广算法设计的条件已基本具备。

Abstract: It has always been a popular research direction in structural design for algorithm replacing engineer’ s manualdebugging， but it has not been widely used in engineering practice. The use of new variables in practical engineering in thestructural design industry were mainly introduced， such as the popularity of more efficient optimization algorithm andprogramming ability in a new generation of structural design professionals， and gradual opening domestic first￣line designsoftware program control interface， and the actual cases which were designed using different algorithms in differentengineering practical problems. The advantages of algorithmic design were introduced. For example， response surfacealgorithm was used to optimize the amount of steel in the design of super￣high building， simulated annealing algorithm wasused to find the curve shape in the design of large￣span canopy， and rapid design update was carried out byparameterization of pile layout in the design of pile foundation. Through these cases， it is concluded that the conditions forthe promotion of algorithm design in structural design industry have been basically met.

Keywords: building structure algorithm design； response surface algorithm； simulated annealing algorithm； optimizationalgorithm； pile foundation parameterization
