Abstract:
An analytical computerized method is used to determine steel, concrete, and bond stresses, as well as bond slip along the steel bar of reinforced concrete axial elements under cyclic loading. Appropriate constitutive curves are used for steel, concrete, and local bond. Analytical tests were conducted on long reinforced concrete tie elements under both monotonic and fully reversed cyclic loading. Transverse main cracks are predicted to form, open, and close during the load cycles. The redistribution of steel, concrete, and bond stresses are calculated during the loading and unloading cycles. The redistribution of steel, concrete, and bond stresses are calculated during the loading and unloading cycles, as well as the presence of residual stress and slip or crack widths at zero external load. Analytical tests were also carried out on pullout elements. Steel, concrete, and bond stresses are determined along a type of pullout element with external shear stresses along its sides.
