The extent of cracking in slabs reinforced with smooth welded wire fabric is determined by the bond and achorage properties of fabric as well as by the magnitude of the steel stress. Test results show that the crack spacing is controlled primarily by the transverse wire spacing and by the size and spacing of the longitudinal wires.

Elements of a theory for the mechanical behavior of concrete are developed. . .This study provides information on the nature of inelastic behavior of concrete by examining its micro-behavior under a short-time loading. Based on this micro-behavior and on statiscal concepts, the study attempts to develop elements of a unified theory for the response of concrete from zero through the elastic, inelastic and descending ranges of the stress-strain curve to fracture.

Fracture of plain concrete under biaxial tensile and compressive stress is investigated. The stress states at inception of microcracking, or discontinuity, and strength are found. Such properties as strength, stiffness and mode of breaking alter with the extent of microcracking in a specimen; the extent of microcracking depends on loading program. Explanations of fracture which overlook these subjects by considering only mean stress at breaking may be faulty. The curve of discontinuity is suggested as a simple, safe criterion of strength for some problems of engineering design.
