Abstract

The effect of good or poor bond along beam and column bars within a joint on shear strength in reinforced concrete interior beam-column joints was investigated. Five interior beam-column joint specimens with one-half scale were tested. The bond along beam and column bars within a joint and loading history were chosen as the test parameters. All specimens eventually failed in joint, shear. The maximum story shear force of the specimens with good bar bond was larger than that of another specimen. The concrete strains at the beam critical section were measured by strain gauges. The depth of the concrete compressive region at beam critical section exceeded a half of the beam depth. The horizontal joint shear force was calculated considering the shape of concrete compressive stress block at the beam critical section. Joint shear force by this method decreased with the decrease in story shear force for the specimen with poor bond along the beam bars.
