However the integrity of post tensioning system is importance for the overall performance of the girder. There are several factors contributing to post tensioning system deficiency this includes inadequate grouting, poor design and defect in construction methods. This deficiency can led to corrosion and bond loss in post tensioned members. The damage caused by different type’s loads especially cyclic load in partially grouted concrete bridge girder is not deeply studied. In this study a finite element model in Abaqus 6.14 is prepared to investigate the damage propagation in partial grouted post tensioned concrete bridge girder with respect to damage initiation and propagation under monotonic and cyclic loading. Different level of grouting are considered to simulate level of partial grouting. The study showed that higher grout levels delayed crack initiation for both monotonic and cyclic load and slightly increased load capacity (from 88.78 kN- 92.41 kN for 10% − 50%)grout level for monotonic load and (10.6 to 103.34kN for 10% − 50% ) grout level for cyclic load.
