Title: Cracking in Reinforced Concrete Flexural Members

Abstract:Tensile cracks, normal to the tensile stress in reinforced flexural members when loads are applied, were investigated in a series of tests of slabs and beams. Spacing of the cracks was measured, crack widths on the tensile face were determined by the use of Tuckerman optical strain gages, strains on the tensile reinforcement were measured with electric resistance strain gages, and deflections of the specimens were measured with taut wires, and scale devices. Location and extent of cracks were observed and reported. Slabs of different widths and beams of different depths and spans, with different bars sizes and percentages of reinforcement in each, were tested under loads applied at the quarter points. Measurement of the width of cracks was confined to that portion of the specimen in which the bending moment was constant.
