The beams are representative of beams used in special moment frames. In the experimental investigation, two beams reinforced longitudinally with Grade 100 steel having tensile-to-yield strength ratio (T/Y) of 1.18 and 1.30 were tested in the laboratory to study the (a) spread of plasticity, (b) inelastic rotation capacity, (c) buckling characteristics and related requirements for transverse reinforcement, and (d) local bond stress-slip relationship of deformed reinforcing bar anchored in concrete. Transverse reinforcement was Grade 100 steel with T/Y of 1.30. Overall, the two beams achieved rotation capacity of at least 0.035. The beam with lower T/Y of 1.18 failed by fracture of longitudinal bars at base of the beam, while the beam with higher T/Y of 1.30 failed by buckling of longitudinal bars over several hoop spacings. Test data given by strain gauges installed on longitudinal bars clearly showed that beam with higher T/Y achieved greater spread of plasticity compared to the other one. In the analytical study, methods and mathematical models to assess strength and force-displacement response were evaluated based on the experimental results. Two additional beam tests are planned in the present test program.
