The extension of the Orly Sud terminal building includes a steel structure measuring approximately 165 meters long, 45 meters wide, and a maximum height of 21 meters. The floors consist of steel to concrete composite slab elements. The facade mainly includes tall glass panels. . Lateral stability is ensured by steel frames in the transverse direction and bracing in the longitudinal direction.
All structural elements (columns, downstand beams, purlins, cross beams, etc.) were modeled in RFEM. This amounted to more than 7,300 steel beams with a self-weight around 1,500 tons. RFEM’s powerful performance made it possible to calculate the overall structure according to second-order analysis with imperfections applied to members for stability considerations.
The nonlinear model included more than 250 load combinations accounting for various global imperfection directions. Steel design was completed in the RF-STEEL EC3 add-on module including the RF-STEEL Warping Torsion extension to also analyze the members with applied torsional moment.
