The Stadium Project in Côte d'Ivoire
Abidjan, the economic capital of Côte d'Ivoire in West Africa, has a tropical maritime climate. The city and its suburbs boast beautiful scenery, with roads built with Chinese aid and buildings constructed with aid from various countries.
The stadium introduced today is a large-scale Class A stadium with 60,000 seats, a total construction area of 61,250 square meters. It includes a football and rugby stadium meeting international standards, an athletics track with eight curved tracks and ten straight tracks next to the main stand, and other functional buildings. It is the largest, highest-standard, and most modern stadium in West Africa.
The stadium canopy uses multiple cantilevered inverted triangular section steel trusses to meet the architectural requirements. Three-dimensional and planar trusses are arranged along the inner ends and the middle circumferentially to solve the overall stability problem of the cantilevered trusses, while also making the canopy a relatively integrated system. The construction process spanned the rainy and dry seasons, and the stadium finally stood on the plain from scratch.
Initially, G-type membrane material was planned for the design phase. However, during construction, after careful consideration, the membrane structure canopy material was changed to P-type membrane material. Both membrane materials have comparable technical performance and unique characteristics. G-type membrane material offers excellent light transmittance and self-cleaning properties, which is the main reason for its popularity both domestically and internationally. Bending resistance is not crucial after the canopy is tensioned, and the transportation limitations of G-type membrane material were only understood after consulting membrane structure technical guidelines. Building materials need to be processed and transported by land and sea; materials that are not resistant to bending may have a high breakage rate. Even if successfully transported to the site, due to the large size of the membrane sheets, damage during installation and tensioning due to wind is almost irreparable. Comparing material prices alone, P-type membrane material is slightly cheaper than G-type. After research, the design, construction, and user parties all agreed to change the canopy membrane material to P-type. During on-site construction, tensioning was completed in one step.
