Abstract:Based on the architectural scheme, a new type of the large span spatial rhombic truss is adopted in Suzhou Railway Station. The main design points about the spatial cross-coupling rhombic truss were introduced, including the structure arrangement, load calculation, static and dynamic analysis, construction simulation analysis, analysis of preventing sequential collapse, analysis of multi-support and multi-dimension excitations. The analysis methods and some conclusions are useful for the similar projects.
Keywords:spatial rhombic truss; construction simulation analysis; preventing sequential collapse; multisupport excitations
