Abstract:Haikou Five-source River Sports Center Stadium adopts unilateral roof structure, most of the stands are on the west side of the building. The west side stands adopts the reinforced concrete frame-shear wall structure, and roof adopts the super-light cable membrane structure. Roof steel structure connects with the outer row of oblique columns, which are used to support the concrete structure of the lower stand, by using the 20 ball bearing supports, and two bearing shear walls are set on both ends to bear the huge horizontal thrust caused by use of non-closed ring roof. The rationality of the simplifying model of the grandstand was analyzed by the final assembly model, and the energy dissipation and shock absorption measures were taken for the high seismic intensity area. The stability analysis of the 36m-long outer row layer-crossing oblique columns, the design measures of the super-long concrete structure, anti-horizontal force foundation design of the shear wall of the northern and southern end bearings. The seismic performance goals of the main components were determined. The results of dynamic elastic-plastic time-history analysis under the action of rare earthquakes show that the structure can reach the seismic fortification goal of "not collapse under rare earthquake.

Keywords:Five-source River Sports Center; performance-based seismic design; energy dissipation and shock absorption; super-long structure; dynamic elastic-plastic analysis
