Abstract:Wanda Ski Center in Harbin is the  largest indoor ski resort in the world, which covers a total floor area of 86 000m2, of which snow surface area covers about 64 000m2. The building is a super-long span structure with unique shape, and its out-of-code structure is complex, so  many design difficulties exist. The special key technical problems of structural design of super-large indoor ski resort were mainly expounded, including load value, design standard, structural system formation, structural torsion and eccentricity optimization, tensile design of ski run floor, anti-sliding test and design on ski run base, research on performance of  steel structure at low temperature, non-uniform vertical force and horizontal force design on foundation, super-conventional node design principles, etc. And a series of measures were put forward such as construction simulation analysis, construction monitoring and health monitoring to ensure the safety and rationality of the structure, which provide reference for design of indoor snow structures.

Keywords:Wanda Ski Center in Harbin;  structure optimization ; tensile design of snow run; anti-slip design; performance of steel structure at low temperature;  design to resist lateral loads
