Abstract: In response to recent terrorist activities, an increasing number of building projects specify design criteria for blast resistance, residual structural integrity, and survivability. Increases in structural system size, weight, and costs are often necessary to meet these criteria with conventional materials, but using higher strength materials offers a way to mitigate these increases while achieving desired performance levels. Accordingly, the U.S. Army Engineer Research and Development Center (ERDC) has investigated the effects of using high strength low-alloy vanadium (HSLA-V) steel reinforcing bar coupled with high strength concrete as a structural system. The primary objective of this research is to develop and characterize a high strength Portland cement concrete, HSLA-V material combination that meets or exceeds blast resistance criteria while allowing a more efficient structural design than can be achieved using conventional materials. Vanadium is widely used as an alloying element in steel production, and micro-alloying vanadium with steel reinforcing bar has been shown to contribute to higher yield strengths, relative to traditional rebar, without compromising ductility or formability. Ten reinforced concrete panels were tested using the ERDC Blast Load Simulator. The panels consist of double mat conventional Grade 60 rebar or HSLA-V rebar in combination with 4 ksi or 15 ksi concrete. The panels had simple support end constraints in the longitudinal (long) direction and were unsupported in the lateral (short) direction. Midspan deflection in the horizontal and vertical direction, the distributed pressure on the front face of the panels and reaction frame, and pressure existing in the target vessel were recorded in these experiments.
