Application of beam string structure in Guangzhou International Covention and Exhibition Center is introduced. Some problems such as linear and non-linear calculation, stability of strut and the influence of the degree of prestress are discussed and compared. The design method provides referrence for design of similar structures.
Keywords:  beam string structure; stability; non-linear analysis; prestress
