STRENGTH, CRACKING AND DEFORMATION SIMILITUDE IN FAILING IN INCLINED COMPRESSION

THE STRENGTH, CRACKING, AND DEFORMATION SIMILITUDE OF FULL, ONE-HALF, AND ONE-THIRD SCALE MODELS OF REINFORCED CONCRETE T-BEAMS WITHOUT AND WITH STIRRUPS AND FAILING IN SHEAR AND FLEXURE IS REPORTED. THE EFFECTS OF AGGREGATE SIZE AND CONTROL SPECIMEN SIZE ARE ALSO INVESTIGATED. THE GREATER DEFLECTIONS AND THE INCREASED STRENGTH CHARACTERISTICS OF MODELS BEFORE FAILURE IS SHOWN TO BE DUE TO THEIR INCREASED STRAIN CAPACITY AND THE PRESENCE OF A STRAIN GRADIENT IN THE COMPRESSION ZONE. FOR STRENGTH AND CRACKING SIMILITUDE IT IS NECESSARY TO SCALE DOWN THE MAXIMUM AGGREGATE SIZE. ONE-THIRD SCALE MODELS CONSISTENTLY SHOW LARGER INCREASES IN STRENGTH. MODELS MADE FROM THE SAME MATERIALS AS THE PROTOTYPE ARE ABLE TO SATISFACTORILY SIMULATE DEFORMATION AND STIFFNESS CHARACTERISTICS OF THE PROTOTYPE. /AUTHOR/
