- Abstract
- Current design philosophy permits moment-resisting frames subjected to seismic loading, apart from a few exceptions, to be induced into the inelastic range where the forces that develop in parts of the structure will exceed their design values. Therefore the joints need to dissipate large energy amounts. Paulay, Park, and Phillips first introduced the idea of using inclined main reinforcement to prevent brittle failure in short reinforced concrete coupling beams. Use of inclined reinforcing bars shows that achievement of high ductility behavior of structural elements is possible in several researches then.This study investigates the improvement in the seismic behavior of exterior reinforced concrete beam-column joints resulting from the presence of inclined reinforcing bars. Specially, to drive the joint brittle failure by the strength increase of beam that there is possibility to happen in general constructions, we designed the full-size specimens of weak-column / strong-beam. The test results show by inclined reinforcing bars that the strength, stiffness, and energy dissipation capacity were improved. But, more studies are required for achievement of high ductility behavior.
