Abstract:
The corrugated soil Steel Structures, consisting of a combination of shells of corrugated steel plates and surrounded with well compacted backfill soil have been used in Sri Lanka for the first time in Southern Transportation Development Project as underpasses and drainage structures. This has been selected for the lower cost and the lesser construction time. In this study the effect of height of soil cover over the structure, on the stress in the steel shell of Metal Arch Underpass (MAUP) structures is analyzed to determine an optimum range for soil cover and to evaluate the structural safety of the prevailing structures. The commercially available Finite Element Software ANSYS, SAP 200 and PLAXIS 1.5 are used in modelling the structures.
