摘要: 算法取代工程師的人工調(diào)試工作一直是一個(gè)比較熱門(mén)的結(jié)構(gòu)設(shè)計(jì)研究方向，但未大量應(yīng)用于工程實(shí)際。主要介紹了實(shí)際工程中，利用結(jié)構(gòu)設(shè)計(jì)行業(yè)內(nèi)出現(xiàn)的新變量，如更高效的優(yōu)化算法、編程能力在新一代結(jié)構(gòu)設(shè)計(jì)從業(yè)人員中的普及、國(guó)內(nèi)一線(xiàn)設(shè)計(jì)軟件逐步開(kāi)放程序控制接口等，針對(duì)不同工程實(shí)際問(wèn)題采用不同算法進(jìn)行設(shè)計(jì)的實(shí)際案例；并介紹了采用算法設(shè)計(jì)的優(yōu)勢(shì)，如在超高層設(shè)計(jì)中采用了響應(yīng)面算法優(yōu)化型鋼用量，在大跨度天幕設(shè)計(jì)中采用模擬退火算法進(jìn)行曲線(xiàn)找形，在樁基設(shè)計(jì)中通過(guò)對(duì)樁布置進(jìn)行參數(shù)化快速設(shè)計(jì)更新。 通過(guò)這些案例筆者認(rèn)為結(jié)構(gòu)設(shè)計(jì)行業(yè)推廣算法設(shè)計(jì)的條件已基本具備。

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
