Abstract:
Corrugated flexible Soil Steel composite culvert or bridge (SSCB) having larger spans are being constructed more frequently around the world. Often, also a low height of cover is necessary. To increase the Free rooms with other profiles than the circular type are being constructed. The paper presents a parametric study of the performance of another two profiles taking the effect of applying geogrids in the backfilling soil to reduce stresses laying on the steel bridge. Finite element modelling (FEM) were implemented adopting software package PLAXIS 2-D version 8.2 non-linear (2004). The results elucidated that the use of geogrid in backfilling soil had significant influence on reducing bending moments in the corrugated steel sheets. The vertical concrete pedestals with arch culverts reduces the bending moments.
