Abstract
Shrinkage-induced cracking in constrained concrete slabs is an important failure mode for concrete structures. Several empirical relations have been reported in earlier studies. This paper develops a mechanics-based relationship for shrinkage-induced cracking through a shear-lag model that can be used to analyze the stress field, crack width, and the final crack spacing for cracked concrete slabs. The present model prediction is observed to be close to the empirical relation based on long-term observations.
