A Direct Design Approach for Strengthening Simple-span Beams With External Post-tensioning

This paper presents the analytical formulation to establish equations for the direct determination of the increase in load-carrying capacity of simple-span beams strengthened by external post-tensioned tendons. Two sets of equations--refined equations and simplified equations--are proposed. By using these equations, the tendon configuration in terms of its profile, area, and eccentricities can be determined for the strengthening of simple-span beams to carry a specified additional load. A design example is given in the appendix to illustrate the application of the method.
