The stiffness of concrete members and the free energy of material degenerate under the continuous temperature change, and the strain error exists. In order to solve the above mentioned problems, Early-age concrete strain error detecting method under continuous temperature change is proposed. Through accurate measurement of concrete strain error, the nonlinear creep model of early age concrete structure under continuous temperature change is deduced. The coupling relationship between material stress and creep is quantitatively analysed to improve the strength of concrete. A method for detecting...
