Axial strain capacity of line pipe subjected to combined loading conditions - An experimental approach in full-scale dimension: LiSA
Proceedings Publication Date
Effects of external loads and ground movements on pipelines have significant influence on the induced strains and thereby on the Strain Based Design aspects. The pipeline’s resistance to multi-axial load scenarios (internal pressure, along with induce pronounced longitudinal strains and multi-axial-stress states) is not fully solved yet. Full-scale testing is the only possible experimental way to determine the pipe behaviour in the plastic regime. The present paper addresses a full-scale pipe bending device developed and put into operation at Salzgitter Mannesmann Forschung (SZMF). The Limit State Analyzer (LiSA) enables the experimental study of the strain-based pipeline behaviour subjected to internal pressure, axial and bending load.
