RFCS Project: “BriFaG”, 2008 – 2011

“Bridge Fatigue Guidance”


– Development of bridge fatigue guidance for

the sustainable design and assessment of

steel bridges subjected to fatigue

– systematic investigation on the fatigue

strength of fillet welds loaded multi-axial

(toe cracking, FAT 71)

– in-plane multi-axial fatigue tests


Pz

– Investigation of principale stress ranges taken

from the strain history measures with

strain gauges

– Determination of rotation of principal stress

angle due to cracking

• Outcome

– EC3 gives safe-sided results for the tests performed

– The amount of shear stress Δτ and its result on the fatigue life under

combined loading rather plays a minor role
