Design and analysis of long-span post-tensioned bonded prestressed cross-beams of a theater

Huang Guohui, Wang Zhigang(Beijing Institute of Architectural Design, Beijing 100045, China)

Abstract:The detailed design process of floor structure and long-span post-tensioned bonded prestressed cross-beams is introduced. Some problems such as degree of prestress, tendon shape and torsion resistance of side main beam are discussed and the treating methods are put forward. Some construction measures for long-span prestressed cross-beams are suggested, and the design experience can be referred to similar engineering.

Keywords:theater architecture; roof structure; prestressed cross-beams; design
