Collapse Load Analysis of Prestressed

This report describes a non-linear method of analysis for prestressed concrete structures which predicts behaviour at all stages of loading, from the initial application of prestress up to and beyond the collapse condition. The method uses a segmental line element approach and is a modification of an existing method previously developed for reinforced concrete structures. Comparisons with the results of tests of continuous prestressed concrete beams show good correlation. The method has been developed for the purpose of investigating the collapse behaviour of indeterminate prestressed concrete structures and hence to develop design recommendations on minimum acceptable ductility levels, moment redistribution and design safety coefficients.
