Shear Reinforcement in Deep Slabs
Abstract
A considerable amount of data is available in the literature regarding the behavior of normally-proportional slabs. Woodson (1993) presented one of the most comprehensive collections of data on statically- and dynamically-tested slabs. The data base was used in the development of the Engineer Technical Letter (ETL) 1110-9-7, "Response Limits and Shear Design for Conventional Weapons Resistant Slabs," published by the U.S. Army Corps of Engineers in September, 1990. The ETL is the most recently published design document on the subject, and it claims no applicability to slabs having span-to-effective-depth (Lid) ratios less than 5. In addition, the ETL sets forth specific shear reinforcement requirements for laterally-restrained slabs with Lid values less than 8. Thus, guidance for shear design and response limits of deep slabs used in protective structures is lacking, particularly for structures to resist the effects of conventional weapons. Thirteen one-way reinforced concrete slabs were statically loaded at the U.S. Army Engineer Waterways Experiment Station (WES) in March through April, 1993. The following sections describe the slabs' construction details, reaction structure, instrumentation, experimental procedure, material properties, and the experimental procedure.
