SHEAR STRENGTH OF REINFORCED AND PRESTRESSED CONCRETE BEAMS SUBJECT TO MOVING LOADS

TESTS WERE MADE ON 19 REINFORCED CONCRETE AND 21 PRESTRESSED CONCRETE BEAMS TO INVESTIGATE THE EFFECT OF INCLINED CRACKING RESULTING FROM A LOAD NEAR THE SUPPORT ON THE SHEAR STRENGTH UNDER A SUBSEQUENT LOAD NEAR MIDSPAN. THE ALTERED SHAPE OF THE CRITICAL INCLINED CRACK DID NOT REDUCE THE STRENGTH OF THE REINFORCED CONCRETE BEAMS EXCEPT WHERE THE SPACING OF THE STIRRUPS WAS GREATER THAN THREE-QUARTERS OF THE EFFECTIVE DEPTH. HOWEVER, SEVERAL PRESTRESSED CONCRETE BEAMS WERE REDUCED IN STRENGTH, PARTICULARLY WHERE THE FAILURE WAS DUE TO INSTABILITY OF THE TOP FLANGE. /AUTHOR/
