摘要: 在應(yīng)對(duì)氣候變化、建筑形式和功能發(fā)展以及數(shù)字化變革的大環(huán)境下，結(jié)構(gòu)工程不斷面臨新的挑戰(zhàn)，迫切需要發(fā)展相應(yīng)的設(shè)計(jì)理論與設(shè)計(jì)方法。 在設(shè)計(jì)過(guò)程中結(jié)構(gòu)設(shè)計(jì)與建筑設(shè)計(jì)是前后相承、相互關(guān)聯(lián)而又互有影響的關(guān)系。 在回顧了過(guò)往的結(jié)構(gòu)設(shè)計(jì)表達(dá)形式后，認(rèn)為新的設(shè)計(jì)場(chǎng)景下的結(jié)構(gòu)設(shè)計(jì)工作將從計(jì)算機(jī)輔助設(shè)計(jì)走向人機(jī)合作設(shè)計(jì)范式，并提出了適合此范式的結(jié)構(gòu)設(shè)計(jì)表達(dá)框架，即結(jié)合參數(shù)化幾何和結(jié)構(gòu)體系元參數(shù)，以有向無(wú)環(huán)圖為基本數(shù)據(jù)結(jié)構(gòu)建立的參數(shù)化模型。 這種表達(dá)框架既可以描述對(duì)結(jié)構(gòu)體系自上而下分解的一般設(shè)計(jì)過(guò)程，也可以引入自下而上的涌現(xiàn)式創(chuàng)新設(shè)計(jì)，并且進(jìn)一步與結(jié)構(gòu)設(shè)計(jì)及優(yōu)化算法結(jié)合，帶來(lái)強(qiáng)大的工作能力。 介紹了這種參數(shù)化的設(shè)計(jì)表達(dá)在北京中信大廈、北京某辦公樓和拉薩貢嘎機(jī)場(chǎng)新航站樓屋頂結(jié)構(gòu)設(shè)計(jì)中的應(yīng)用。

關(guān)鍵詞: 結(jié)構(gòu)設(shè)計(jì)； 設(shè)計(jì)表達(dá)； 參數(shù)化； 優(yōu)化算法； 人工智能

Structural design representation in human￣machine partnership design paradigm

Abstract: The ever￣changing outer environment has posed new challenges to structural engineering， including the climatechange， the development in architectural typology and functionality， and the digital transformation.It is urgent to developcorresponding design theory and design method. The relationship between the structural design and the architectural design isforminga consequential， consecutive and interactive during the design process. Based on the review on the existing structuraldesign representations， it is deemed that the structural engineering is changing gradually from computer￣assisted design to ahuman￣machine partnership design paradigm under the new design circumstance. A structural design representation frameworkunder this paradigmwas thereafter proposed， i.e. a parametric model based on directed acyclic graph(DAG) data structurewhich combines the parametric geometry and the meta￣parametric representation of structural systems. This expressionframework can not only describe the general design process of top￣down decomposition of structural system， but also introducebottom￣up emergent innovation design. The integration of this design representation further combined with structural designand optimization algorithm can bring powerful working ability. The application of this structural representation in CITIC TowerBeijing， an office tower in Beijing and Lhasa Gongga airport terminal roof were introduced.

Keywords: structural design； design representation； parametric； optimization algorithm； artificial intelligence
