摘要

To test the temperature stress and deformation of the major platform in Nanjing Olympic Sports Center, 8 shrinkage members and 3 creep members were poured on the worksite for comparison analysis. With finite elements analysis, gliding rubber supporters were used on all the pillar tops. The floor stress would be in a constant compressive stress with pre-stress and post-cast-span. This method makes the appearance and developments of structure cracks under effective control. Under temperature changes, the buildings were ensured not to have damageable cracks. This project was passed with super quality.
