Abstract:The 107m large-span saddle-shaped single-layer cable net structure was adopted in the natatorium of Suzhou Olympic Sports Center. The influence of wind friction was taken into account in the calculation; the overall stability analysis of the structure was carried out considering geometric nonlinearity and material nonlinearity; the corrosion tests of stress-free non-coated cable, stressed non-coated cable and stressed coated cables were carried out; the research on the influence of large deformation of flexible roof on the auxiliary structure was completed; the large deformation test of the roof system was carried out; the steel roof health monitoring system was set up. The results of calculation and test show that each index of the structure can meet the requirements of the code. The health monitoring system shows that the measured stress and deformation fit well with the calculated value during the construction and use stages of the structure.

Keywords:Suzhou Olympics Sports Center; single-layer cable net structure; wind friction; accessory structure; stability analysis; cable corrosion; health monitoring
