Metalúrgica Vera S.R.L
Metalúrgica Vera S.R.L. was awarded the design and construction of a new hangar structure located in Paraguay’s Silvio Petirossi International Airport for large aircraft repair and storage.
The building includes seven steel frames spaced 7.7 meters on-center. The walls are a pre-cast thermo-acoustically insulated concrete system. The roof cladding includes sandwich panels supported by cold-formed lightweight steel sections.
Two hinged frames with welded tapered cross-sections span 213 ft in length. The column cross-section depth is ~ 1.6 ft at the bottom and ~ 6.6 ft at the top. The frame beams are tapered at the start as well as at the span middle. With the strong bracing system, the structure was designed to withstand 180 km/h 3-second gust wind loads which is required by the 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 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.
