The structural system of Suzhou Taicang Alps Snow World is reinforced concrete frame structure,and a plane truss system is used for the roof.Out-of-code properties such as torsional irregularity,inconsistent slab,eccentricity ratio greater than 0.15 and split-level exists in the structure,thus the building is an out-of-code high-rise building.The foundation form,the structural system,the load evaluation,and the performance goal of the structure were introduced.Elastic calculation was performed by using three different programs YJK,PMSAP and MIDAS Gen.Paco-Sap was also used to carry out the dynamic elastoplastic analysis.The key problems in ski area structural design was stated,such as story drift ratio,long and short columns,key joints of the truss structure and temperature load.The calculation results show that the indicators such as the period ratio and the story drift ratio all meet the requirement of standard requirements.By carrying out performance-based design and dynamic elastoplastic analysis,the designed structure and its components are able to satisfy the stated performance goal under moderate and rare earthquakes.Strengthening measures were also adopted targeting critical areas and key components.
