Data collected from shake table tests of two, approximately one-third scale, two story flat plate frames utilizing shear reinforcement, as well as data from prior tests, were evaluated to assess the inter-story drift ratios when punching failures occur for reinforced concrete and post-tensioned slab-column connections with and without shear reinforcement. The drift ratios at punching for the sh...

Understanding the effects of repair on reinforced concrete (RC) structures is critical to evaluating their performance in future earthquakes. In this research, a system-level approach taken by repairing previously damaged ¼ scale 4-storey RC structure and subjecting it series dynamic excitations via shake table testing. The was undertaken using common construction materials with primary motivat...
