(北京市建筑設計研究院，100045)［提要］單層索網幕墻具有通透的建筑效果，同時設計過程較為復雜，對周邊支承結構也提出了較高的要求。結合財富中心單層索網幕墻結構設計，研究了具有較柔邊框的雙向受力索網幕墻體系的設計和倒拆法施工方案。對結構模型的選取、荷載工況的組合和單層索網的預應力張拉設計進行了深入研究。預應力施工張拉方案分別按索內力設計值的50%，80%，100%進行，設計方法是方便有效的。［關鍵詞單層索網；幕墻；預應力；施工方案Design of Single layer Cable Net and Analysis of Prestress Control Technology for Lobby of Prosper Center/Sheng Ping,Zhen Wei(Beijing Institute of Architectural Design， Beijing 100045， China)Abstract: Single layer cable net curtain wall with light weight and fine transparence is difficult to design, and raises critical demand for the supporting structure. Referring to the design scheme of single layer cable net of Prosper Center, the design of single layer cable net curtain wall and supporting system with minor stiffness is studied, and the construction method is raised. The analysis model choosing, load combination, prestress construction design of cable net are thoroughly analyzed. The design method is proved to be efficient through practice.Keywords: single layer cable net； curtain wall; prestress； construction method
