Abstract:A method of estimating distribution of expansive strains produced in members of rectangular cross section with reinforcing bars arranged in any manner based on measured values of standard uniaxially restrained specimens is proposed. This method adopts the hypothesis that work performed by expansive cement concrete on restraining reinforcement is a constant value regardless of quantity and method of arrangement of reinforcement, and is a convenient met which does not include constants such as modulus of elasticity and creep coefficient of expansive cement concrete. Errors between estimated and measured values are approximately 20% at maximum, and the accuracy may be said to be adequate for practical purposes.
