The present paper addresses issues of pipeline design associated with unintended actions due to external loads or ground movements. These may introduce longitudinal strains in the pipeline owing to combinations of curvatures and axial forces. Such scenarios must be tackled with Strain-Based Design approaches. The following sections elaborate on the strain capacity of HFI-welded pipes checked via material testing and a full-scale test performed on a pressurized HFI-pipe under bending load. Analytic modeling procedures for predicting the structural behavior using certain assumptions are described.
