Abstract：
Wuxi Taihu International Expo Center Phase II covers a relatively large plane area and wide spatial span. After comparison and selection, temporary support is set on floor, roof structure is lifted in segments by crane erected outside the span and then the roof is unloaded separately. Structural model is established by using finite element computation software to simulate key states in practical construction and to verify stress, deformation and other data fed back during construction. Construction problems are successfully solved.
