Lacing and Stirrups in One-way Slabs

Abstract : The overall objective of this study was to better understand the effects of shear reinforcement details on slab behavior to improve the state-of-the-art in protective construction design, for both safety and cost effectiveness. This was not particularly a study of shear stresses in slabs, but rather a study of the effects of shear reinforcement on the large deflection behavior of slabs. Specifically, the objective was to evaluate and compare the effectiveness of stirrups and lacing bars in enhancing the ductility of one-way slabs. This included a consideration of how shear reinforcement details interact with other physical details to affect the response of a slab. The work reported herein was directed toward the development of new guidelines for designing shear reinforcement in blast-resistant structures.
