- Abstract
- Eight half-size and four full-size T-shaped reinforced concrete exterior beam-column subassemblies were tested to determine the effect of intermediate longitudinal shear reinforcement on the hysteretic behavior of flexural members subjected to repeated reversed loading. Specimens were tested by applying a constant axial load to the fixed column portion of the specimen and applying a cyclic shear load to the beam. The beam typical loading history was chosen to simulate the distortion which might take place at a typical connection in a ductile moment-resisting frame during a severe earthquake. Several conclusions were drawn on the basis of test results.
