The shrinkage deformation of 28 commercial concrete members is measured on series 360days,and the concrete age,the compressive strength,the environmental condition and the dimension of member are analyzed in detail.Based on 67 experimental data,considering the effect of the concrete age and the compressive strength,the basic formula of shrinkage is gained under standard condition by aggression analysis;Furthermore,the multi-coefficient formula of shrinkage for commercial concrete under non-standard conditions is gained by Multi-coefficient superposition method,and in the formula,the temperature-relative humidity coefficient and the dimension coefficient are considered.The calculation result of the multi-coefficient formula agrees well with the 130 experimental datas.
