Abstract:Theoretical derivation for a typical structural model and finite element analysis of Bao’an stadium in Shenzhen were carried out in order to investigate temperature effects on cable force. Obvious deviation of cable force from its design value was not expected, so three measures for correcting deviation of cable force were proposed for Bao’an Stadium, and it will remove the temperature effects mentioned above. These measures were proved to be effective in Bao’an Stadium.
Keywords:spoke structure; construction; temperature effect; Bao’an Stadium
