［摘要］石家莊國際展覽中心采用雙向懸索結(jié)構(gòu)，結(jié)構(gòu)建模及分析過程中，存在大量的找形及優(yōu)化過程。為提高工作效率，項目在找形、建模、分析、優(yōu)化、數(shù)據(jù)處理等設(shè)計過程各環(huán)節(jié)均采用了參數(shù)化技術(shù)。通過研發(fā)增量式更新和派生式建模技術(shù)，避免了項目調(diào)整時結(jié)構(gòu)工作不得不重新開始的情況，同時也加快了相似單體的創(chuàng)建速度。參數(shù)化技術(shù)的研發(fā)和應(yīng)用使項目設(shè)計效率發(fā)生了根本性的變化。借助于參數(shù)化技術(shù)平臺，設(shè)計師得以集中精力于結(jié)構(gòu)的方案比較與優(yōu)化工作，從而提高了設(shè)計質(zhì)量。本項目的參數(shù)化應(yīng)用說明在高復(fù)雜度結(jié)構(gòu)設(shè)計中，參數(shù)化技術(shù)相對于傳統(tǒng)設(shè)計方式優(yōu)勢巨大。

Abstract:Shijiazhuang International Exhibition Center adopts the bidirectional cable structure. In the process of structural modeling and analysis, there were a lot of form-finding and optimization processes. In order to improve the work efficiency, the parametric technology was used in the project in all aspects of the design process such as form finding, modeling, analysis, optimization, and data processing. Through the development of incremental updates and derived modeling technologies, the situation that structural work had to be restarted during project adjustment was avoided, and the speed of creating similar single building models was also accelerated. The development and application of parametric technology radically changed the efficiency of project design. With the help of parametric technology platform, designers concentrated on the comparison and optimization of structural schemes, thereby improving the design quality. The parametric application of this project shows that in high-complexity structural design, the advantages of parametric technology over traditional design methods are huge.
Keywords:Shijiazhuang International Exhibition Center； bidirectional cable structure; parametric; structural optimization; incremental update; derived model
