Analytical model for bond-slip behavior under monotonic loading

Abstract

In this paper the distributions of bond stress, slip and strain are analyzed. The local bond-slip law is idealized by a piecewise linear relationship, for each part of which closed-form solutions are obtained for bond stress, slip and strain distributions. The steel bar length is divided into four zones in the general case. Conditions of continuity between zones and boundary conditions are used to solve the length of zones, and strain and slip distributions. Simultaneous transcendental equations are obtained and solved using Newton's tangent method. The analytical predicted results compare well with test results in tension and compression.
