![]() the wind. The top of the tower is capped by a monumental structure symbolizing an architectural Phoenician sail. Tower is composed of 26 floors and 3 underground basements. It is 155 m high and has a total built-up area of around 44,000 m with exceptionally long cantilevers reaching a maximum of 7 m. The adopted slab system was a cast-in-situ post-tensioned flat plate, which accelerated the floor construction cycle, alleviated the building's own weight and minimized the interference with electro-mechanical services. The typical basement floor system relies on reinforced concrete flat slab with drop panels. core wall in the center and frame system at building periphery. The dual shear walls and frame systems are sized to control the effects of eccentricity between the center of mass and the center of rigidity of the structural skeleton. picks up the gravity and lateral loads from the superstructure down to the ground floor structure. The foundation is a 2.8-m thick raft. Wind tunnel testing was performed to verify the wind loading adopted in the design and ensure human comfort. consists of moment-resisting steel frames (tubular column and beam sections) stemming from the periphery of the roof floor. The sail-supporting columns are fixed on the concrete roof at three different elevations (+126, +121 and +116) and have a freestanding height of 20 to 40 m. |
