Factors governing redistribution of moment in continuous prestressed concrete beams

The failure load of a continuous prestressed concrete beam depends partiall y on the amount of redistribution of moment that occurs prior to failure. R esults from a parametric study, carried out using a nonlinear finite elemen t computer program, are presented to demonstrate the influences of various factors on redistribution of moment in two-span, continuous bonded prestres sed concrete beams. Trends in the data from the numerical studies are compa red with those from a theoretical expression for percentage of redistributi on, and it is shown that the redistribution of moment occurring in a contin uous prestressed concrete beam is a function of number of parameters.
