Abstract:
An approach is proposed for determining the percentage of redistribution of moment occurring at failure of a continuous prestressed concrete beam. The approach, which is based on two parameters--the percentage of redistribution x and the moment ratio MR--was developed using results from nonlinear finite element analyses of a large number of continuous prestressed concrete beams. In the proposed approach, the available redistribution of moment is based on the overall structural behavior rather than on the cross-sectional behavior.
