Abstract: Chord tension trusses with 99m and 72m span were adopted for large span roof of Xiamen International Conference and Exhibition Center phase Ⅲ. Concrete counterweight was used to prevent the great wind uplift. Twoway truss and combination floor system with TMD systems were used to reduce the floor vibration for the local 27m span across floor. The new roof system, roof wind tunnel test results and wind load for design, parameter selection method of temperature effect analysis, the calculation results of chordtension truss and the concrete roof, the construction control rules, and other key design contents were introduced for large span roof. The combination floor system, floor vibration calculation and TMD vibration reduction were introduced for large span floor.

Keywords: large span roof; floor; chordtension truss; TMD; vibration reduction; counterweight
