Addendum to Prestress Analysis for Continuous Beams: Some Developments in the Equivalent Load Method by B. K. Catchick

The equivalent load method is a technique for replacing a prestressing tendon by a system of external, statically equivalent loads. Bending moments induced in the member under the latter system of loads will represent the total prestressing effect and can be determined by any of the existing techniques for analysing indeterminate structures. Consequently, the method is useful because derived equivalent loads may be employed as input data to computer programs for direct evaluation of the total prestress moments (including secondary moments) for a continuous beam.
