This paper briefly describes the calculation principles for the creep coefficient in the GFR-Code 《DIN-4227》. According to the delayed elastic deformation theory, a revised formula of the age-adjusted effective coefficient ρ is derived from the "Age-Adjusted Effective Modulus Method" asUsing the method proposed by the author, the calculation of the sedondary moment due to concrete creep in the continuous girder bridge constructed with the span by span method is analysed and discussed here.The main conclusions are as follows:1. The accurate value of the age-adjusted effective coefficient ρ is not necessary in the calculation of the secondary moment due to creep in the continuous girder bridge.2. We suggest that the applicable range of the coefficient p be 0.5 to 0.55 when the load is applied for a short time and 0.6 to 0.7 when applied for a long time.

The analysis for concrete creep and shrinkage is a common problem in the bridge structural analysis, and there are many popular methods available now. On the basis of the global incremental equation, this paper presents an automatic incremental creep and shrinkage analysis method which is easy to implement by using the modern computer technology, include its principle and features compared with other methods. Taking the development of the new generation of bridge integrated CAD system——BRCAD as the application background. This paper gives a brief introduction to the implementation. An example of the creep analysis for a continuous girder bridge constructed with span by span method is also given to prove its accuracy and practicable.
