Abstract: Based on the architectural scheme,a new type of the large-span thombic spatial truss is adopted in the Suzhou Railway Station. The key techniques are presented about the roof structure formed with thombic cross-coupling trusses, including the structural arrangement, load combinations, dynamic and statistic analysis, construction simulation and analysis of preventing sequential collapse, etc. The analytical methods and some conclusions are useful for the similar projects.
Keywords: rhombic spatial truss; construction simulation, preventing sequential collapse analysis
