main steel structure of lignite-fired power station

All platforms and the furnace are fastened at the main steel structure. The main horizontal loads are also stabilized by the maiin steel structure.
Half of the platforms (~80m-140m) are hanging in final position at the cantilevers of the main steel structure.
At the backside the flue gas duct (d~15m) is also hanging at cantilevers at the main steel structure.
Because of site conditions and because of missing wall cladding very high windloads have to be considered.
Due to high loads all sedtions are box sections. The design of all members, plate buckling design and connection design according to EC3.
