［摘要］石家庄国际展览中心采用双向悬索结构，结构建模及分析过程中，存在大量的找形及优化过程。为提高工作效率，项目在找形、建模、分析、优化、数据处理等设计过程各环节均采用了参数化技术。通过研发增量式更新和派生式建模技术，避免了项目调整时结构工作不得不重新开始的情况，同时也加快了相似单体的创建速度。参数化技术的研发和应用使项目设计效率发生了根本性的变化。借助于参数化技术平台，设计师得以集中精力于结构的方案比较与优化工作，从而提高了设计质量。本项目的参数化应用说明在高复杂度结构设计中，参数化技术相对于传统设计方式优势巨大。

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
