Abstract: A considerable amount of data is available in the literature regarding the behavior of normally proportioned slabs, those with span-to-effective-depth (L/d) ratios greater than approximately 8. However, guidance for shear design and response limits of deep slabs (L/d < 6) used in protective construction is lacking. Thirteen one-way reinforced concrete deep slabs were statically loaded with unifonn water pressure to gain a basic understanding of the behavior of deep slabs with reinforcing details typical of protective construction. The post-ultimate behavior of the slabs indicated that a substantial amount of reserve capacity is available in deep slabs with large quantities of principal reinforcement. Based on this series, the recommended response limit for deep slabs having a principal steel ratio near 0.01 and adequate shear reinforcement is approximately 12 deg. For deep slabs with relatively small quantities of principal steel, the response should probably be limited to approximately 8 deg for design purposes.
