Temperature response in concrete under natural environment

Abstract Temperature variation in natural environment was conducted in order to predict the action spectrum of temperature under natural environment by substituting the model to the segmented fitting method. A novel method based on the measured data was proposed to solve the concrete thermal parameter. Results showed that the temperature variation of the concrete and natural environment periodically fluctuates, and the theoretical action and response spectra of the temperature agree well with the measured results. The presence or absence of sheltered condition has a significant effect on temperature response in concrete in terms of the amplitude, extreme value and arising time.
