Raffles City Chongqing, China
RCCQ won the top award in the Mainland/Overseas category. A mega-scale development at the heart of Chongqing, the project comprises a shopping mall and eight towers for residential, office, serviced residence and hotel use. To address challenges brought by the conservatory over four towers, we proposed dynamically linked method that allows the conservatory to move freely over four towers which might response differently during wind and seismic actions. Furthermore, for the two super slender 350m buildings with a slenderness ratio of 9.4, Arup adopted four mega columns schemes connecting with outrigger trusses and perimeter belt trusses o form an effective structural system and withstand winds and earthquakes.
