CRACK WIDTH CONTROL IN TWO-WAY CONCRETE SLABS REINFORCED WITH WELDED WIRE FABRIC-PART I

THE EFFECT OF TWO-WAY ACTION ON THE CRACK WIDTH DEVELOPMENT IN CONCRETE SLABS IS BEING STUDIED, AND THE MANNER IN WHICH SUCH BEHAVIOR IS AFFECTED BY VARYING TO EXTREMES THE DIAMETER AND SPACING OF THE MESH AND THE PATTERN OF THE WELDED JOINTS IS BEING DETERMINED. IN THIS MANNER A CRITERION COULD BE DEVELOPED FOR LIMITING THE CRACK WIDTH OF THE CRITICAL CRACKS TO LEVELS ACCEPTABLE FOR PERMISSIBLE REINFORCEMENT PROTECTION, DEFLECTION AND AESTHETICS. THE MAJOR FACTORS THAT AFFECT CRACKING ARE THE FOLLOWING: STEEL REINFORCEMENT STRESS AND CONSEQUENTLY THE TENSILE STRAIN, THE TENSILE SPLITTING STRENGTH OF THE CONCRETE, THE BOND STRESS BETWEEN THE STEEL AND THE CONCRETE (WHICH IS A FUNCTION OF THE SQUARE ROOT OF THE COMPRESSIVE STRENGTH OF THE CONCRETE), THE MESH INDEX, (WHICH GOVERNS THE FORMATION AND SPACING OF THE CRACKS), IT IS THE RATIO 01S2/PTL, NAMELY A PARAMETER DEFINING THE MESH REINFORCEMENT PATTERN AND THE CONCRETE STRETCHED AREA), AND THE CONCRETE STRETCHED AREA MENTIONED ABOVE (WHICH IS THE AREA OF THE CONCRETE SECTION WHICH IS STRETCHED IN TENSION). /AUTHOR/
