Experiment-8: Test of Conventionally Reinforced Frame Beam at Aspect Ratio 3.33 (FB33)
Experiment Type: Large Scale
Description: This experiment consists of cyclic testing of a conventionally reinforced concrete coupling beam, or a reinforced concrete frame beam. The beam has aspect ratio (ln/h) 3.33 to represent typical office construction. The specimen is designated as FB33 or Beam 8. As the aspect ratio increases, the angle of the diagonal reinforcement decreases, reducing the benefit of the diagonal reinforcement while increasing the difficulty of construction. The purpose of the experiment is to provide a control study with which to compare the benefit of diagonal reinforcement in higher aspect ratio beams. Results indicate that the diagonal reinforcement provides much higher ductility and energy dissipation. However the frame beam is substantially easier to construct and so if required rotation levels are low, it may be the better option.
