Addressing lateral loads at the Marsa Sports Complex required the use of cross-bracing to ensure structural rigidity behind the continuous glass curtain wall, while maintaining transparency. The Macalloy tension system was chosen for its efficiency and aesthetic appeal. Cross-bracing connections to the concrete structure were made using angle connections cast directly into the concrete, facilitating load transfer to and from the horizontal rigid floor diaphragms.
The design process was informed by advanced finite element modeling, which analyzed forces and stresses within the steel connections. Fabrication was carefully monitored, with periodic inspections and independent testing of welds to ensure they could bear the tension and shear forces from lateral loads. Despite logistical challenges during site installation, careful planning and collaboration enabled the successful installation of connections, even in areas with significant reinforcement. Positioned at the building’s front corners, these cross-bracing connections play a crucial role in conjunction with other lateral elements, transferring loads to the underlying rock stratum through inclined piles—a topic that will be explored in future discussions.
