【摘要】：柯橋收費站大跨度罩棚采用剛架結構體系,結構由共五榀大截面實腹箱形剛架組成,剛架跨度85.1m,矢跨比約1/19,跨中高跨比為1/65,剛架柱向外傾斜11°,支承在10個抗震球鉸支座上。針對罩棚結構大跨度、低矢跨比、低高跨比等特點,詳細介紹了結構設計過程,并著重介紹了整體穩(wěn)定性能分析、防連續(xù)倒塌分析和關鍵節(jié)點分析,可供同類工程設計時參考。
[Abstract]:The large span canopy of Keqiao toll station is composed of five large section solid web box frames. The span of rigid frame is 85.1 m, the ratio of rise-to-span is about 1 / 19, the ratio of middle to high span is 1 / 65, the column of rigid frame tilts outward 11 擄, and it is supported on 10 earthquake resistant spherical hinges. In view of the characteristics of large span, low rise-span ratio and low height span ratio of the canopy structure, the design process of the structure is introduced in detail, and the analysis of overall stability performance, continuous collapse prevention analysis and key node analysis are emphatically introduced, which can be used as a reference for similar engineering design.
