STRENGTH AND DEFORMATION CHARACTERISTICS OF PLAIN CONCRETE SUBJECTED TO HIGH REPEATED AND SUSTAINED LOADS

THE EXPERIMENTAL PROGRAM SHOWED THAT CONCRETE RESPONSE TO HIGH REPEATED LOADS IS TIME-DEPENDENT FOR STRESSES HIGHER THAN ITS SUSTAINED LOAD STRENGTH. FOR A MAXIMUM STRESS HIGHER THAN THE SUSTAINED STRENGTH, A DECREASE IN THE STRESSS RANGE AND/OR THE STRESS RATE (TEST FREQUENCY) SIGNIFICANTLY INCREASES THE "SUSTAINED LOAD" CONTRIBUTION TO THE OVERALL BEHAVIOR. IN THE ANALYTICAL STUDY, A DAMAGE MODEL WAS DEVELOPED IN WHICH THE CYCLE AND TIME-DEPENDENT EFFECTS ARE EXPRESSED SEPARATELY. AN ANALYTICAL MODEL TO DETERMINE THE FAILURE STRAIN MODEL WAS DERIVED. /AUTHOR/
