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.

Principal Investigator:


Prof. Jaap Wardenier, Delft Univ. of Technology, The Netherlands.
