Abstract:
This paper presents results from an experimental investigation in which thirteen rectangular reinforced concrete beams were subjected to cyclic loading within service conditions. One beam was designed to measure the variation in steel stress and bond stress along the beam length, particularly between cracks and in the anchorage zones near the beam ends. The variables in the other twelve beams included the area of concrete concentric with each tension rebar and the ratio of compression reinforcement to tension reinforcement. Resulting bond deterioration is analyzed and its effect on bond stress distribution as well as crack development is illustrated and discussed.
