A detailed investigation is reported on the flexural cracking behavior of two-way concrete slabs reinforced with cold-drawn plain high strength welded wire fabric: Large scale square slab panels were used. They were simply supported or clamped and were centrally loaded. Crack width propagation was observed with illuminated microscopes at close space intervals on the major cracks. Strain in the wire reinforcement was electronically recorded in the locations where the crack widths were observed. Compressive strain in the concrete and deflection at critical locations were also measured. The size and spacing of the wire were varied in the different specimens to observe their effect on the cracking behavior.
