Abstract: The lateral force resisting system,seismic performance-based design,design of mountain buildings,etc. on themain structure of the National Ski Jumping Center ( Xueruyi) project was introduced in detail,including the seismicperformance-based design method,the measures taken according to the structural characteristics and the foundation design.The seismic performance-based design objectives of the structure were given,and the response spectrum analysis,elastictime history analysis,rarely-occurred earthquake dynamic elastoplastic analysis and special analysis of key parts of thestructure were carried out. According to the characteristics of mountain building foundation,a reasonable foundation schemewas selected,and targeted measures were taken to ensure the structural safety. At the same time,the overall eccentric largeoverhang of the top building has brought great tension to the foundation and main structure. Through targeted measures suchas section steel and prestressed rock bolts,the overall stability of the structure was ensured.
