［摘要］蘇中江都機(jī)場(chǎng)航站樓鋼屋蓋為波浪式雙曲屋面，屋蓋結(jié)構(gòu)結(jié)合建筑造型要求，采用了多榀鋼屋架+單層四邊形斜交網(wǎng)格的結(jié)構(gòu)體系。針對(duì)鋼屋架、斜交網(wǎng)格等不同方案以及抗側(cè)力構(gòu)件的分析、比較，確定了合理的結(jié)構(gòu)方案。鋼屋蓋的動(dòng)力特性和靜力分析表明結(jié)構(gòu)具有可靠的受力性能。選用屋蓋構(gòu)件截面、連接節(jié)點(diǎn)時(shí)充分考慮了外露結(jié)構(gòu)的美觀要求，結(jié)構(gòu)較好地體現(xiàn)了建筑形態(tài)和設(shè)計(jì)理念。

［關(guān)鍵詞］鋼屋蓋；屋架連續(xù)梁；單層網(wǎng)格結(jié)構(gòu)；抗側(cè)力構(gòu)件；彎折板節(jié)點(diǎn)

Abstract: To meet the requirements of architectural design, wave-like hyperbolic steel roof and single-layer quadrilateral oblique crossing grid are used in the structural system of Suzhongjiangdu Airport Terminal. The steel roof, oblique crossing grid and lateral force-resisting members were analyzed to determine the reasonable structural system. Dynamic and static characteristics of the steel roof were researched and the results have proved that the structure has reliable mechanical performances. Aesthetic requirements of exposed structure were considered when selecting the section of steel roof members and connections. Architectural modeling and design concept are reflected well in the structure.

Keywords: steel roof; continuous beam; single-layer grid structure; lateral force-resisting member; bending plate joint
