The most common wind tower structure, a tapered tubular steel monopole, is currently
limited to heights of~ 80 m due to transportation constraints which arise because tower …

The present investigation refers to the bending capacity of spiral-welded steel tubes. The
first part of this investigation presents the results of a full-scale experimental program, aiming …

Spiral-welded steel tubes (SWTs) are fabricated by helically bending a steel plate and
welding the resulting abutting edges. These tubes enable larger diameters, longer joint-less …

A new manufacturing process allows for the production of tapered spirally welded steel
tubes. This paper describes a series of eight large-scale tests examining the behavior of …

Since the discovery of reserves in arctic regions, operators have been faced with a number
of challenges, including assessing appropriate methods of transporting produced …

Durability and maintenance considerations may necessitate the use of stainless-steel for
concrete-filled steel tube structural elements. The cost-effectiveness of such concrete-filled …

This study investigated the capability of widely-used finite element modelling (FEM)
methods, to predict the flexural capacity behaviour of concrete-filled spiral-welded mild-steel …

Pipeline transport is one of the main solutions for oil and gas transmission and distribution.
The pipeline in service may be subjected to complicated loads (internal pressure, tension or …

The mechanical behavior of spiral-welded large-diameter steel pipes is simulated, with the
purpose of defining their bending deformation capacity against local buckling. The steel …

The first part of this paper provides a review of recent investigations on steel pipes subjected
to combined loads. Attention is given to studies involving both numerical and experimental …
