Following the previous paper, this shows a step-by-step calculation method to estimate long-term curvature of concrete slab section on which certain moment force is imposed supposing that the dry shrinkage strain distributes along the section as an equal amount, i.e. rectangularly distributed. Compared to the values calculated according to the triangularly distributed shrinkage strain, they have small difference; especially the thickness of the member is large. Latter part of this paper describes the difference between the modified elasticity method which has been employed in Japanese building standard for reinforced concrete structure for long time as a simple evaluation method, and the step-by-step method depicted in this and the previous paper. This study shows that the modified elasticity method is effective as a rough evaluation, and the difference becomes larger as the amount of compressive reinforcement increases.
