(北京城建設(shè)計研究總院，北京100037)[摘要] 中關(guān)村西區(qū)景觀平臺位于中關(guān)村廣場的核心區(qū)域，是隨著廣場逐級升高而形成的架空兩條城市支路的空中景觀平臺。景觀平臺采用多種復(fù)雜空問鋼結(jié)構(gòu)體系。其結(jié)構(gòu)設(shè)計有別于普通鋼結(jié)構(gòu)的設(shè)計方法：從方案一開始結(jié)構(gòu)工程師就和建筑師一起參與建筑形態(tài)與合理結(jié)構(gòu)體系的研究，把握力與形的關(guān)系，建筑與結(jié)構(gòu)的設(shè)計趨于一體化?；仡櫫酥嘘P(guān)村西區(qū)兩個大型景觀平臺鋼結(jié)構(gòu)的設(shè)計方法及過程，介紹了主要結(jié)構(gòu)構(gòu)件和節(jié)點的計算及處理方法；并對將建筑美學(xué)與結(jié)構(gòu)形態(tài)的結(jié)合做了初步的探討。

(Beijing Urban Engineering Design&Research Institute, Beijing100037, China)Abstract: 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.
