  2. Creep analysis methods of high - rise buildings and large span buildings can only refer to creep coefficient method in bridge engineering or the method of degree of creep in hydraulic construction engineering under the present experiment conditions. in this paper, the incremental expressions of concrete creep and shrinkage strain when the initial computational age is not the same as the loading age are derived and corrected from the concept of concrete creep coefficient and the mean value theorem of integral and the principle of superposition. the differences of efficiency and accuracy of creep analysis between the finite element method with creep coefficient and the initial stress method with degree of creep are presented. this paper suggests that engineers should use the initial stress method with degree of creep to estimate the influences of creep on high - rise buildings and large span buildings on the basis of conceptual design
