| Abstract: | One-way prestressed steel beam string structure was used in the roof of exhibition part of culture and sports center in Sanmenxia City.The cable force was difficult to control because of its complex structure and large span.Prestress construction schemes were compared and analyzed,and tension scheme were selected which was tensioning at both ends and by degrees.The stretching forces of the cable was optimized.Cable force,deformation and steel structure stress were simulating analyzed. |
