2019北京世园会入口大门结构优化设计
|
摘要
限额设计是项目在可行性研究阶段基于以往同类工程的投资估算,以经济性为优先考虑因素的设计要求。以2019北京世园会主入口大门的结构设计为例,针对限额设计提出了一系列优化措施,通过结构方案比选、结构布置优化、构件截面验算、建筑高度和轮廓调整、楼面墙面材料选取等几个方面对结构进行了优化设计,在保证建筑功能需求和建筑方案效果的同时使结构受力更合理,建造成本更节约。
Limits designing is the design requirement based on the investment estimation of similar projects during feasibility research, taking economical factor as the priority. Taking the structural design of the main entrance gate of International Horticultural Exhibition 2019, Beijing, China as an example, a series of optimization measures were put forward to meet the requirements of limits designing, thus optimizes the structure design from structural scheme comparison, structural layout optimization, component section optimization, building height and contour adjustment to building material selection. The measures made structural stress more reasonable and the construction cost more economical while guaranteeing the functional requirement of the building and the effect of the building scheme.
