Fatigue Design Guide for Circular and Rectangular Hollow Section Multiplanar Joints
Sponsor:
European Convention of Steel and Coal (ECSC).
Partners:
Delft University of Technology, The Netherlands
University of Karlsruhe, Germany
TNO Bouw, The Netherlands.
Objective:
The research aimed at investigating the capacity of welded tubular connections, under fatigue loads. Using finite element analysis, stress concentrations at the weld vicinity of a wide range of tubular joint geometries and sizes were measured. Applications, involve offshore structures, bridges, masts and towers.
