Beam-column joints are critical elements in a special moment resisting frames as they govern the structural behavior and failure mechanisms under extreme events such as earthquake, blast, and impact. This work was undertaken to investigate the dynamic response of a reinforced concrete (RC) external beam-column sub-assembly subjected to shockwave. To this effect, a well-instrumented shock tube setup was developed to investigate the dynamic response of the joint. The shock-induced transient displacement and acceleration were measured at discrete locations along the length of the beam, and the entire shock event was recorded using a high-speed video camera. The maximum displacements acquired th..View full abstract
