Introduction Concrete creep is a very complex problem for concrete structures especially pre-stressed concrete structures, it is not only related to the material properties, but also closely related to the applying load, tensioning time, the location of concrete, environment temperature, humidity, as well as many other factors [1, 2], and the exact value can’t be determined based on the current calculation of the theoretical and experimental means [3, 4].
