新北京中心项目结构与建筑方案设计的融合

Integration of structural and architectural scheme designs for New Beijing Centre project

超高层建筑方案设计需要建筑师和结构工程师从方案设计前期就开始紧密配合。概念方案设计阶段,建筑师往往会深挖当地的文化内涵及城市的特点进行创作,以期塑造一个独一无二的城市新地标。这对于结构工程师提出了如下两个挑战:结构的布置需考虑保证建筑效果的实现;结构自身的安全性和经济性。以新北京中心项目结构方案设计为例,通过不同结构方案的比选,包括:建筑立面收分形式的研究、外框结构不同选型及布置的研究、核心筒平面布局的研究及承重墙体的选择、底部入口不同转换结构形式的研究,来阐述建筑与结构专业相互融合方案设计的过程。

The design of super high-rise buildings requires architects and structural engineers to work closely together from the beginning of the design process. At conceptual design stage,architects often dig deep into local cultural connotations and the characteristics of the city to create a unique new landmark in the city. This poses two challenges for structural engineers:the layout of the structure needs to consider the realization of the building effect;safety and economy of the structure itself need to be considered. Taking the design of New Beijing Centre project as an example,different structural schemes were compared and selected and specific works included research on the indentation form of building facades,research on the selection and arrangement of different structural systems of outer frame structures,research on the layout of corewall and selection of load-bearing walls,research on different transformation structural forms of bottom entrance structure. All above research were used to illustrate the process of the integration of structural and architectural scheme designs.
