Research on the Creep Material Nonlinearity of UEA Expansive Concrete
In this paper, the creep experiment of UEA expansive concrete is performed. Based on the creep experiment results, the creep model of UEA expansive concrete is gotten by Curve Fitting function supplied by ANSYS. By comparing the residual error, the modified time hardening equation is recommended to simulate the primary stag constitutive relation of UEA expansive concrete and the primary + secondary time hardening equation is recommended to simulate the whole constitutive relation of UEA expansive concrete. Besides, when calculating by ANSYS, the suggestions about the selection of the expansive concrete element type are given.
