Structural Analysis of Prestressed Concrete Continuous Beams for Ultimate Moment Calcalation

In structural analysis of prestressed concrete continuous flexural mambers, secondary effects produced by tendon forces should be reasonably estimated. The secondary moment at service load stags is normally used for ultimate required moment caculation in strength design. This concept has to be reviewed when precise analysis is performed considering construction step, time dependent properties of concrete and tendon. An ultimate moment computation proposed, concept and structural behavior. The previously proposed procedure by other researcher and the proposed procedure are compared and reviewed for the currently constructed precast prestressed concrete bridge.
