Prediction of the Effects of Creep of Concrete Under Non-Uniform Stress

Abstract

The problem of predicting the stresses and strains in a plain concrete member subject to sustained non-uniform stress is investigated. Two theoretical methods of solving this problem are presented. Both were used to predict the strains and stresses of four eccentrically-loaded plain concrete prisms which formed a part of an experimental program. The experimental program also furnished data necessary for both of the theoretical approaches. It is concluded that the two methods are useful, and that they may be easily modified to deal with problems involving the sustained load characteristics of reinforced concrete members.
