Abstract:
Creep has important effects on the st’resses and deflections of reinforced and prestressed structures. Concrete structures in use are subject to variable stress whereas most of the data on creep have been obtained under constant, stress. It is therefore desirable to he able to compute creep under variable stress from the results under constant stress. Three met,hods for doing this are discussed and experimentIs designed to test these methods are described. Each method has a certain advantage in particular circumstances depending on the character of the stress variation, the extent of creep data available, and the accuracy required.
