An Analysis of Drying Shrinkage within a Concrete Structure

Abstract

This paper presents an analysis of drying shrinkage within a concrete structure. If drying shrinkage is in proportion to water content, the governing equation for drying shrinkage can be directly solved by F. E. M.
First, the analytical results of a 10×10×40cm specimen were found to be in agreement with the experimental results obtained by Kiyama et al.
Secondly, the analysis of a real structure showed small drying shrinkage at the surface following placement. This implies that the proper choice of K and f is important.
Also, drying shrinkage stress was calculated using the thermal stress equation.
Finally, a new equation has been proposed for this calculation.
