摘　　要：针对大跨度钢连廊因制造误差、焊接残余应力以及安装误差等原因会造成实际承载能力较理想设计模型存在偏差的问题,本研究以扬州建工科技园A2~A3双塔楼间连廊作为研究背景,根据《建筑结构可靠性设计统一标准》GB50068-2018和《城市桥梁检测与评定技术规范》CJJ/T233-2015利用蓄水法作为静力荷载对连廊进行静载试验,对其承载能力进行研究,结果证明该连廊符合安全性要求。Aiming at the large-span steel corridor due to manufacturing errors,welding residual stress and installation errors and other reasons will cause the actual load carrying capacity of the ideal design model deviation,this study to Yangzhou Construction Engineering Science and Technology Park A2~A3 double towers between the corridor as a research background,according to the"Unified Standard for Reliability Design of Building Structures"GB50068-2018 and the"Urban Bridge Inspection and Evaluation Technical Specification"CJJ/T233-2015 static loading test of the corridor using the water storage method as a static load to study the carrying capacity of the corridor,and the results proved that the corridor meets the safety requirements.
