Abstract

Shrinkage stresses caused by random variation of environmental humidity in a long cylindrical concrete wall sealed at the internal surface are analyzed, taking creep and aging of concrete into account. The random time-variation of humidity and stress is analyzed by the spectral method using the elastic-viscoelastic analogy. Spatial variations are described by Bessel and Kelvin functions. Numerical examples typical of a 1 m thick reactor containment and a thin shell of 10 cm thickness are given.
