LOAD-CARRYING CAPACITY OF SLAB STRIPS RESTRAINED AGAINST LONGITUDINAL EXPANSION

THE RESULTS OF TESTS ON 36 BEAMS (CONSTRUCTED TO REPRESENT SLAB-STRIPS) RESTRAINED AGAINST LONGITUDINAL EXPANSION ARE REPORTED, AND A THEORY, WHICH IS BASED ON THE RIGID-PLASTIC APPROACH, PUT FORWARD FOR THEIR BEHAVIOR. IT WAS FOUND THAT IN MANY CASES THE EXPERIMENTAL MAXIMUM LOAD WAS EVEN GREATER THAN PREDICTED BY THIS THEORY, WHICH CAN BE EXPLAINED BY ASSUMING THAT THE CRUSHING STRENGTH OF THE CONCRETE WAS GREATER THAN THE CUBE STRENGTH. SUPPLEMENTARY TESTS ARE DESCRIBED WHICH SUPPORT THAT ASSUMPTION. IT IS SHOWN THAT THE DEFLECTION AT MAXIMUM LOADS IS NOT A FIXED PROPORTION OF THE THICKNESS OF THE SLAB, AS HAS BEEN ASSUMED IN SOME THEORIES. /AUTHOR/
