Aircraft Hangar at Silvio Pettirossi International Airport | Luque, Paraguay

The building includes seven steel frames spaced 7.7 m (25.26 ft) on-center. The walls consist of a prefabricated thermo-acoustically insulated concrete wall system. The roof cladding includes sandwich panels supported by cold-formed lightweight steel sections.

Two hinged frames with welded tapered cross-sections span 65 m (213 ft) in length. The column cross-section depth is about 0.5 m (1.6 ft) at the bottom and 2 m (6.6 ft) at the top. The frame beams are tapered at the start as well as at the span middle. Thanks to the strong bracing, the system can withstand 3-second wind gust loads of 180 km/h (111.85 mph), as required by Paraguayan wind standard NP 196. In combination with the purlins, the bracing elements also prevent lateral-torsional buckling of the frame beams.

The basic steel design was calculated in RF‑STEEL, while the code design was calculated in RF‑STEEL AISC. After the initial design, the 3D model was created in Tekla Structures to maximize quality and minimize delays during construction.
