Abstract: Inner Mongolia Autonomous Region Art Museum has a construction area of approximately 36 000m2, and is a landmark building in Hohhot. The project is a particularly complex structure with L-shaped plane, including spatial inclined plane, twisted surface, suspended and large cantilever structures. Firstly, the determination of the structural system was introduced, and it focused on the four aspects to explain how the structure achieved the beauty of architecture, including the external curtain wall system, building interior space, horizontal and vertical traffic of building and floor comfortableness. Secondly, the design difficulties in the overall structure and key parts were considered. Several analyses were conducted on the cantilever steel structure including the overall static analysis, performance-based seismic analysis, complex joint analysis, overall stability analysis and progressive collapse analysis, and corresponding measures were taken. The results show that the overall structure is safe and reliable.
Keywords:art museum; suspended and large cantilever; performance-based seismic analysis; progressive collapse
