摘要：The mathematic manual drivation is conducted to solve the classical creep and shrinkage system of differential equations of composite beams. By the differential multipier, the differential system is similar to the algberic system and can be solved analytically. The analytical formulars of the reditributed internal forces are obtained and they are useful for further research although it is complicate. The results of deduced formulars have been compared with those obtained by computer software.
