BEHAVIOR OF CONCRETE UNDER BIAXIAL STRESSES

EXPERIMENTAL STUDIES INTO THE BIAXIAL STRENGTH OF CONCRETE ARE REVIEWED AND TECHNICAL DIFFICULTIES ENCOUNTERED IN THE DEVELOPMENT OF A SUITABLE TEST SETUP ARE DISCUSSED. A NEW TESTING APPARATUS IS DESCRIBED WHICH ALLOWS TESTING OF CONCRETE SPECIMENS UNDER VARIOUS BIAXIAL STRESS STATES. RESULTS OF AN INVESTIGATION FOR WHICH THIS EQUIPMENT WAS USED ARE REPORTED. THE TEST DATA INDICATE THAT THE STRENGTH OF CONCRETE UNDER BIAXIAL COMPRESSION IS ONLY 16 PERCENT LARGER THAN UNDER UNIAXIAL COMPRESSION. TESTS IN THE REGION OF COMBINED COMPRESSION AND TENSION CONFIRMED PREVIOUSLY OBTAINED DATA. THE BIAXIAL TENSILE STRENGTH OF CONCRETE IS APPROXIMATELY EQUAL TO ITS UNIAXIAL TENSILE STRENGTH. /ACI/
