［提要］廣州白云機場東三、西三指廊為一期擴建工程項目，結(jié)構(gòu)設(shè)計上作了較大的改進。指廊鋼屋蓋采用了預(yù)應(yīng)力拉索拱形鋼管桁架，有效地減小了桁架的結(jié)構(gòu)高度，改善了桁架的內(nèi)力分布。桁架支座節(jié)點采用了鑄鋼節(jié)點，既滿足了復(fù)雜的受力要求，又達到了較好的建筑效果。

Structural Design of Guangzhou New Baiyun Airport East Ⅲ and West Ⅲ Airside Concourses/Liao Xuzhao (The Architectural Design and Research Institute of Guangdong Province, Guangzhou 510010, China)
Abstract: The east Ⅲ and west Ⅲ airside concourses are parts of the phase I extension project of Guangzhou new Baiyun airport. There is great improvement in structural design. Prestressed arch truss is applied to the roof of the airside concourses. The prestressing force and the archshape make the internal force of main truss more uniformity，and the structure depth of main truss is reduced. Cast steel is adopted in the joints, which brings satisfying solution to the problems of complicated structure and forces, and makes the architectural effect of the joints more pleasing.
