| Abstract: | The foundation slab of the complex building of Beijing Television Center is 2 m thick (some part reaches 6.5 m), 88.2 m long in east-west direction and 77.45 m wide in north-south direction. In the construction, crack control technology was successfully applied, concrete continuously placed in one time, no any later-poured belt or construction joint reserved during concrete placement. By months of observation, no penetrating crack or other harmful crack is found, and concrete quality meets the requirement. |
