R/C Member Cyclic Response During Various Loadings

Abstract

An experimental investigation to determine the effect of variations in displacement history sequence and magnitude on cyclic response of reinforced flexural members is presented. Testing variables included shear stress as well as displacement history. Test results indicated that both member behavior and member energy dissipation capacity were functions of applied shear stress intensity and the magnitude of maximum displacements applied to the members. It was found that cantilever beam specimens of the type tested could endure many cycles of loading for all shear stress levels as long as beam‐tip displacement did not exceed 2% of beam shear span length.
