The space grid structure which used the square pyramid grid structure form was adopted as the roof of Suzhou University Gymnasium.The support which supported by frame columns through seismic spherical bearings was the lower chord multi-support point form.SAP2000 was used to analyze the construction process of steel roof.The analysis included the lifting process and the unloading process.The analysis results show that the measured deflection values are in good agreement with the theoretical calculation values.These provided a scientific basis for the construction process of steel structure roofs.
