Abstract:The National Speed Skating Oval（NSSO）is the landmark venue of the 2022 Winter Olympic Games in Beijing. The roof of the NSSO adopts a single layer two-way orthogonal cable net. The giant ring truss is placed in the outer ring, which is supported on the grandstand inclined column. The grandstand inclined column using to support the roof is the reinforced concrete column. Some key problems and corresponding treatment measures in the design of the main structure of NSSO were expounded, including structure foundation design, over limit situation, seismic performance-based design, elastoplasticity under rare earthquake, calculation of the bearing capacity of the giant column and so on. It provides a reference for similar engineering design.

Keywords:National Speed Skating Oval; giant column; overlength structure; foundation settlement; performance-based design; elastoplasticity under rare earthquake
