Moment-curvature characteristics of prestressed concrete sections Available to Purchase

Moment-curvature relationships, obtained from eight geometrically similar critical sections of four two-span post-tensioned beams and sixteen geometrically similar critical sections of four post-tensioned portal frames with fixed feet, are examined. Element and sectional behaviour is suggested that reasonably predicts the moment-curvature relationship of similar sections which occur at different points in the same structure.
