Experiment contributed by Santiago PujolThis test was part of an experimental program that included a total of eight test assemblies. An assembly consisted of two test specimens joined by a center stub. Each specimen was intended to represent a cantilever column under axial load and a point transverse load applied at its end. The center stub was intended to act as the base of the cantilevers.
Each test assembly was supported by rollers at the ends of each cantilever. Cyclic lateral load reversals were applied at the center stub. Axial load was applied using external postentioning rods.
The cross section of the specimens was 6-in. wide and 12-in. deep. The shear span (a = distance from the support point to the nearest face of the center stub) was 27 in. and the effective depth (d) was 10 in., for a shear span to effective depth ratio (a/d) of 2.7. The longitudinal reinforcement consisted of four continuous 3/4 in. diameter bars with an average unit yield stress of 65.7 ksi. Transverse reinforcement outside the center stub consisted of hoops made from plain 1/4 in. diameter bars with an average unit yield stress of 59.6 ksi. Average concrete strength ranged from 4100 to 5200 psi.
