Reinforced concrete roof exterior wide and conventional beam-column joints under lateral load

摘要

Performance of beam-column joints at roof level is one of the areas needing research in ACI 352R-02. Thus, behavior of roof exterior beam-column joints was evaluated by testing two half-scale roof wide and conventional beam-column joints effectively confined on three vertical faces under lateral quasi-static cyclic loading. Both of the specimens had conventional transverse beams. They were designed in accordance with ACI 318-11 and ACI 352R-02 provisions. It became clear by the tests that roof exterior wide beam-column joint was more ductile compared with roof exterior conventional beam-column joint. But there was not considerable difference between strength and energy dissipation capacity of the specimens. Moreover, joint shear strength was sufficient in wide beam-column joint. Therefore, joint shear requirements can be relaxed for roof exterior wide beam-column connection. Copyright (C) 2015 John Wiley & Sons, Ltd.
