Axial compression capacity of welded-slip pipeline joints
(2007)Using advanced numerical tools, which account for the cold-expansion manufacturing process, the axial capacity of welded slip pipeline joints under compressive loading is investigated. The numerical results are in good ... -
Bending deformation capacity of large-diameter spiral-welded tubes
(2014)Numerical simulations are conducted to define the bending deformation capacity of large-diameter spiral-welded tubes, towards efficient strain-based design. Under bending loading, the principal failure mode of those tubes ... -
Bending instabilities of elastic tubes
(2002)The present paper examines instabilities of long thin elastic tubes. Both initially straight and initially bent tubes are analyzed under in-plane bending. Tube response, a combination of ovalization instability and bifurcation ... -
Buckling and classification of high-strength steel CHS tubular members under axial compression and bending
(2012)EN 1993-1-1 provisions classify high-strength steel CHS members with relatively low values of D/t ratio as Class 3 or 4, so that their strength is based on elastic behavior only, neglecting their capability of sustaining ... -
