摘要]蘇州重元寺大禪堂屋蓋采用了鋼混凝土組合空腹夾層板結構體系,屋蓋屋面總荷載達到約15kN/m2,屋蓋平面尺寸為50.7m×33.4m。通過對比原3層鋼網架設計方案,說明該體系在大荷載和大跨度屋蓋設計中經濟性能優(yōu)越、建筑使用功能優(yōu)良。對該體系設計中常遇到的與框架柱相連的肋梁超筋、排水找坡和受壓上肋配筋較大的問題,分別給出了肋梁簡支于框架梁、整體結構起坡和僅加高上肋的解決方案。結果表明,這些處理方式切實有效地解決了上述難題;同時介紹了該體系的簡化計算方法和特殊節(jié)點做法。

Abstract:The roof of meditation hall in Suzhou Chongyuan Temple  adopts structural system of steelconcrete composite openweb sandwich plate with a total load of 15kN/m2 and the plane dimension of 50.7m×33.4m. Compared with the original threelayer steel truss design scheme, it was illustrated that the system has superior economy performance and excellent service performance in heavyload and largespan roof design. To solve the commonly encountered problems of overreinforcement rib beam connected with the frame column, drainage and largereinforcement in upper compressed rib beams, solutions were given as rib beam simply supported on the frame beam, overall structure slope and only upper rib beam heightened. Results indicate that these treatments effectively solve the above problems. A simplified calculation method of the system was also introduced as well as special node details of the structural system.

Keywords:steelconcrete composite structure; openweb sandwich plate; heavyspan; heavyload
