Cracking due to drying shrinkage in an RC wall. Part 2: Proposal of estimation equation

Abstract

The analysis method based on the bond analysis was proposed to estimate cracking behaviour resulting from drying shrinkage of a reinforced concrete (RC) wall, and the validity of this method was verified from experimental study However, there is a shortcoming because the calculation is complex and a simple estimation method is needed. Accordingly, for the estimation of the drying shrinkage cracking (crack width, number of cracks) and the quantitative crack control design of an RC wall in the buildings, improved and simple equations based on the bond analysis were proposed in this paper, and the calculation values were compared with the experimental values and investigation values by the field study.
