Abstract: |
The main subject area of this contribution is the recent development of composite bridges in Europe using welded steel truss girders made of circular hollow sections. The governing criterion for the design of such tubular structures with welded nodes often is fatigue. Comparison between cast steel nodes and welded nodes is made. Also, the beneficial effect of weld peening on the fatigue strength is mentioned. Finally, a brief summary on the development of a new shear connection for prefabricated concrete deck elements is made. |
