(College of Civil Engineering of Southeast University, Nanjing 210096, China)Abstract: Combining with the course of string beam construction in Shanghai Expo 2010 Theme Pavilion, authors study the cable tension analysis and construction control method. Using stress relaxation method, authors determine the construction strength and construction sequence, and present the construction control points.
Keywords: prestress; string beam; construction analysis
