Experimental and numerical investigation of the bending capacity of spiral-welded steel tubes
(2016)To investigate the structural behaviour of large-diameter spiral-welded steel tubes under bending, a full scale experimental program has been performed, consisting of thirteen 42-inch diameter, spiral-welded steel tubes ... -
Fatigue resistance of welded steel tubular X-joints
(2020)High-cycle fatigue experiments are performed on welded tubular steel X-joints, with braces and chord of equal diameter. They are scaled-down joints, used extensively in offshore wind platforms. Three different welding ... -
Interaction of retaining structure with adjacent building: Multi-stage numerical analysis
(2012)Large settlements induced to a multi-store building at the initiation of the construction of a diaphragm wall led to a demand of re-dimensioning the initial retaining measures. To achieve this target a multi-stage numerical ... -
Local buckling limits of tubular sections in bending and compression
(2010)In design standards and recommended practices a large scatter can be observed in local buckling limits. Some can be explained from different design focuses and safety requirements but much is not clear. The traditional ... -
Performance Assessment of a Steel Wind Turbine Tower Subjected to Repeated Earthquakes
(2022)As the wind market grows rapidly and wind power plants are installed in high seismicity areas, there is the increased need for researchers and practitioners to assess the dynamic performance of Wind Turbine (WT) structures ... -
SCFs and fatigue design of multi-planar tubular DT-joints
(2001)The present paper concerns the fatigue design of multi-planar welded tubular DT (double T) steel connections. Stress Concentration Factors (SCFs) are used for the calculation of the hot-spot stress of the joint and, ... -
Strain-Based design procedures for spiral-welded steel tubes in combined walls
(2016)Spiral-welded steel tubes with diameter to wall thickness ratios between 60 and 140 are often employed in combined wall systems with local buckling as governing failure mode. The current design rules in Eurocode 3 (EN ... -
Strain-based design rules for Spiral-welded tubes using analytical modelling
(2016)Spiral-welded steel tubes with diameter to wall thickness ratios between 60 and 140 are often employed in combined wall systems with local buckling as governing failure mode. In a European research project called Combitube, ... -
Structural behavior and design of high-strength steel welded tubular connections under extreme loading
(2020)The present work is motivated by the increasing need for cost-efficient solutions in offshore structural systems for wind energy production and for improvement of their structural performance. The structural behavior and ... -
Ultimate bending capacity of spiral-welded steel tubes - Part I: Experiments
(2016)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 to investigate the structural ... -
Ultimate bending capacity of spiral-welded steel tubes - Part II: Predictions
(2016)In the second part of this investigation, numerical simulations are conducted using nonlinear finite element simulations, to define the bending strength and deformation capacity of large-diameter spiral-welded steel tubes. ...
