中关村西区景观平台的结构设计

Structure morphology in the landscape terraces of Zhongguancun square

中关村西区景观平台位于中关村广场的核心区域,是随着广场逐级升高而形成的架空两条城市支路的空中景观平台。景观平台采用多种复杂空间钢结构体系。其结构设计有别于普通钢结构的设计方法:从方案一开始结构工程师就和建筑师一起参与建筑形态与合理结构体系的研究,把握力与形的关系,建筑与结构的设计趋于一体化。回顾了中关村西区两个大型景观平台钢结构的设计方法及过程,介绍了主要结构构件和节点的计算及处理方法;并对将建筑美学与结构形态的结合做了初步的探讨。

The two steel landscape terraces are located in the core region of Zhongguancun Square.These two terraces raise levels along the Square sequence and span two main roads.This is a Sino-French cooperating project.Several special space structure systems are used in the design.From the very beginning of design,structural engineers joined the group of architects to make together the architectural form and reasonable structure system and to assure the relationship between force and form.This article introduces the design method and processes retrospectively and presents the calculation of main structural members and construction design,at the same time,a preliminary research was made in the combination of architectural aesthetics and structural morphology.
