The football stadium in Mazatlán, with a capacity for 25,000 spectators, is home to the local team that plays in Mexico’s First Liga. The stadium is partially built into a basin and consists of a large grandstand organized on one level on the south side and two levels on the north, east, and west sides. From the outside, the stands are surrounded by a curved membrane facade, the upper part of which forms a canopy of varying dimensions along the perimeter, partially covering the grandstand.
The main structure of the grandstand consists of prefabricated reinforced concrete elements assembled on site with special reinforcement details, connecting them to the concrete poured on site. The prefabricated columns are joined to on-site footings, which support various beams using short brackets, forming the frame structure covered with prefabricated prestressed T-beams. The exterior metal structure consists of a series of curved trusses of varying heights, distributed along the entire perimeter of the stadium, and connected to the various levels of the grandstand, where they transfer their loads. These trusses of varying heights are connected by an upper perimeter ring and intermediate elements that support the enveloping membrane.
Engineer Alberto Cervantes Lugo from JCR Estructural was responsible for ensuring the structural safety of this project in accordance with current Mexican regulations. To do this, he created a spatial model in RFEM of the entire reinforced concrete frame structure and metal trusses, applied the loads to them, and carried out the corresponding strength, stability, and serviceability design checks in the add-on modules.
