Abstract:S3# building of Donghai Torch Science Park in Xiamen is a large-span single-layer latticed shell structure with multi surfaces. There are many flexural-torsional components in this building. Overall mechanical analysis was conducted on the structure by programs of SAP 2000 and ANSYS using finite element analysis method. Prevention of progressive collapse analysis was finished by demolishing components method. Full-range analysis on the sing\|layer latticed sheel  structure was completed on the basis of the consideration of initial geometric imperfection. The result shows that the overall mechanical behavior can meet force requirements, and the progressive collapse can be avoided. Safety coefficient corresponding to the ultimate bearing capacity of the single-layer latticed shell is less than limit value.

Keywords:S3# building of Donghai Torch Science Park in Xiamen; single layer latticed shell; progressive collapse; initial geometric imperfection; overall stability; full range analysis
