Abstract: The building height of Zhejiang National Fitness Center is 61m. It is a sports and fitness venue that verticallysuperimposes multiple functions and large spaces vertically stacked. It adopts a steel frame ( steel truss) -concrete shearwall structure, and the uniformly distributed shear walls form the main lateral force resistance system. The gravity load ofthe large-span sports venue is transmitted to the foundation through the concrete-filled steel tubular column. YJK, ETABSand MIDAS Gen programs were used to compare and analyze the structural overall indexes, internal forces and deformationsof important trusses, and the calculation results from the three programs are consistent and credible. The comfortablenessdesign and strengthening measures of the large-span sports venue were introduced, and the stress conditions of the largespan transfer truss and the working performance of the structure under various actions were studied through constructionsimulation analysis, and the finite element stress analysis of the nodes was carried out. The calculation results show that thevertical vibration acceleration of the structure can be well controlled by using TMD; the stress concentration can beeffectively relieved and the stress level can be controlled by setting appropriate stiffeners at the connection parts of theplates; the structural force transmission path is direct and clear, and the structural system reasonable, safe and reliable.

Keywords:Zhejiang National Fitness Center; sports and fitness venue; large-span truss; comfortableness; node stressanalysis; construction simulation
