| Abstract: | In the Students Activities Center Project of Tianjin Middle School No. 1, large-span prestress-welded spherical grid was adopted. Quality control measures were established for the key points of the construction, such as grid positioning, the effects of temperature on materials in winter construction, reliable operation platform, connection of grid with the main structure etc. After construction, observation and analysis were made on the deformation of the grid structure, and the results satisfied the design requirements. |
