Abstract:The main structure type of the main hall in Confucius International Cultural Exchange Center is reinforced concrete frame-shear wall structure. The triangular steel truss is used in the  cantilevered terrace with the span of 12m on the edge of the fourth-floor. The circular-steel-tube crossed truss system is applied to the roof, and the steel reinforced concrete beam and plane steel truss are used in some large-span floors. The steel reinforced concrete columns are applied to the key vertical members of the steel roof, large-span floor and cantilever truss. Some major problems and corresponding treatment mearsures during the design were mainly introduced, including the design of out-of-code structure, the seismic performance design, the calculation of vertical seismic action and comfort degree of super long-cantilever structure, node analysis of the key supporting member.

Keywords: out-of-code structure; super long-cantilever structure; seismic performance design; vertical seismic action; comfort degree
