TRANSCRIPT
“Modeling Older-Type Reinforced Concrete Corner Beam-Column Joints for Progressive Collapse Simulation” Reinforced concrete (RC) buildings constructed prior to the introduction of ductile detailing principles in the 1970s commonly do not have joint transverse reinforcement. Such “unreinforced” joints, especially those at the edges and corners of buildings, have proven vulnerable to damage and collapse in past earthquakes. For the mitigation of the collapse risk in older concrete buildings, accurate progressive collapse tools need to be developed. An overview of developing such tools using the “element removal” approach will be presented emphasizing recent developments in modeling seismically-‐deficient RC beam-‐column joints. In addition, key results from tests of four full-‐scale RC corner beam-‐column joints without transverse reinforcement will be presented. Finally, preliminary progressive collapse simulations for non-‐ductile RC frames will be presented.
