| Abstract: |
OA666 bridge on the new part continuing the A4 highway in Luxembourg towards France (structure completed in 2017-2019) shows the interest steel-concrete composite solutions for modern infrastructure projects. The deck is extremely slender: the central parts spans 50m with a constant structural height of 1.35 m. The geometry is a bit complex since the road axis follows a clothoidal path with a minimum radius of 640m in the horizontal plane and crosses an existing roadway with a variable skew angle. The construction site is encercled by existing local roads and a lake. The steelwork (total weight 1300 tons, total length 126m) is realized entirely in S460 thermo-mechanical steel with material thicknesses up to 100mm. |
