Abstract

Abstract

In this paper,the true response of a prestressed conrete beam for shrinkage and creep effects have been tested. The results of data analysis illustrate that the strain of concrete consistent with the previous data of shrinkage and creep. As compared to the total strain of 201 d,the proportion of concrete strain in 100 d was close to 75%. As compared to the predicting models of JTG D622004 code,ACI 209R-1992 and China Academy of Building Research(1986), the early test results approximated to the model of ACI 209R-1992,whose changes in late period approximated to the model of JTG D622004 code. Revised test results coincided to those of the predicting models.
