A research was carried out to assess the effect of concrete creep on long-term performance of skewed Integral Abutment Bridge. Time-history transient analysis was conducted using Finite Element method for 75-year period. Parametric study was conducted in LUSAS to assess the effect of bridge total length (60m,90m,150m), skew angles (00 ,100 ,200 ,300 ,400 ), backfill soil stiffness (dense sand, loose sand) on the behaviour of the bridge measured by girder and abutment displacement, moment and shears. Three dimensional nonlinear thick beam element with CEP-FIP 1990 creep material properties was used to model bridge girders. Other structural members were modelled …
