Abstract: Design guides and manuals for blast-resistant reinforced concrete structures require the use of shear reinforcement (lacing bars or stirrups) to improve performance in the large-deflection region of response. It is generally known that the cost of using lacing reinforcement is considerably greater than that of using single-leg stirrups due to the more complicated fabrication and installation procedures. A thorough study of the role of shear reinforcement in structures designed to resist blast loadings or undergo large deflections has never been conducted. A better understanding of the effects of shear reinforcement on large deflection behavior will allow the designer to determine the benefits of using shear reinforcement and to determine which type is most desirable for the given structure. This capability will result in more efficient or effective designs as reflected by lower cost structures. Results of an experimental study comparing the effects of stirrups and lacing are presented.
