Abstract:Taking Zhengdong Campus gymnasium of Affiliated Middle School of Tsinghua University as an example, common large-span floor structures were compared and analyzed, such as prestressed hollow floor, prestressed concrete beam-slab floor, steel truss + concrete slab floor and steel-concrete composite beam floor, and the key points of the design were discussed. The structural design of steel-concrete composite beam floor for the comprehensive training hall and the structural design of steel truss with casting in site concrete floor in the basketball hall were introduced in detail.The comfort and vibration problems of large-span floor structure were discussed, and the checking calculation and vibration control methods were put forward respectively.

Keywords:Zhengdong Campus gymnasium of Affiliated Middle School of Tsinghua University; large-span floor; comfort; vibration control
