Abstract :
A shrinkage stress analysis method is proposed for concrete slabs with shrinkage strips employed as temporary joints to reduce shrinkage cracks in a multistory building. The developed method considers the effects due to creep, external restraint, and construction sequence. The analysis results of an example building demonstrate that the effect of the shrinkage strips can be easily estimated by this method. The effect of stress relief, which is dependent on the number and closing time of shrinkage strips, is also presented. A simplified method is developed and a design recommendation for the shrinkage strip is presented.
