Behavior and Design of Deep Structural Members Part 4: Dynamic Tests of Reinforced Concrete Deep Beams

Tests of simply supported reinforced concrete deep beams, subjected to rapidly applied loads are described in this report. Five beams were tested under a triangular-shaped pulse and three beams were tested under a flat-top pulse of 'infinite duration'. Five beams were tested statically to serve as control beams for the beams tested dynamically. Studies of the relationships of the sum of the measured reactions to deflections, steel strains and concrete strains are made. Data concerning the effects of strain rate on the behavior are presented.Research Directorate, Air Force Special Weapons Center. Kirtland Air Force Base.Contract AF 29(601)-468Project 108
