The creep shrinkage of concrete is an important factor in the long-term deformation of concrete structures. It is also a key link for solving long-term deformation calculation accuracy and complex calculation forms. In this paper, a 1200-day long-term deformation test was conducted on beams with 0%, 50%, and 100% substitution ratios of recycled coarse aggregate. Meanwhile, based on the principle of virtual work, the creep coefficient of recycled concrete is introduced into the calculation of additional curvature of the beam section, and the formula for calculating the long-term deformation of recycled concrete is established. According to the size of recycled coarse aggregate, through the calculation of creep and shrinkage of concrete, the regeneration adjustment coefficient of concrete creep and shrinkage, the calculation results into three typical model of ordinary concrete creep and shrinkage, creep and shrinkage of concrete and regeneration model of deformation calculation of long period, the calculated and experimental results agree well; based on this, the deflection increase coefficient is proposed, which simplifies the long-term calculation formula. It not only can meet the calculation accuracy requirements, but also can be easily adapted to engineering promotion.
