Abstract:
A procedure for prediction of the amount of creep and shrinkage strains is outlined based on the present state of the art. Consideration is given to the loading history of columns in multistory buildings which receive their load in as many in-rements as there are stories in the building, thus considerably reducing the creep as compared to a single load application. Also, volume-to-surface ratio of sections and the effect of reinforcement on the creep and shrinkage is considered.
