Abstract

Abstract

Based on research on crack control of the large platform of Nanjing Olympic Center,experiments on elastic modulus,shrinkage,creep of C40 shrinkage compensation concrete were comducted and some conclusions were achieved from results of these long-term tests.Aiming at control of crack of this structure,it was put forward that design of concrete structures with large longitudinal length should be integrated with actural material characteristics and construction process to realize a dynamic design.
- concrete,
- elastic modulus,
