    Meihua Aviation Technology is building a large third-party flight training center for central and southern China in Huashan, Huadu District, close to Baiyun Airport. The campus covers 129.2 mu (about 86,000 m\u00b2) with 227,837 m\u00b2 above ground and 54,260 m\u00b2 below, and houses flight simulator halls, classrooms and support buildings.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

    Each atrium truss is a single-plane Pratt truss with welded H-section chords and H or tube web members, pre-cambered to offset dead-load deflection. Trusses were split into three segments for road transport, with splice positions chosen at low-moment zones and detailed as end-plate or flange-plate bolted joints with high-strength bolts.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

    Out-of-plane stability comes from purlins, roof bracing between truss pairs and fly braces to the bottom chord. During erection, the first two trusses were braced together as a stable pair before the rest were lifted and tied in.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
