摘要
利用X射线应力测定技术对浦东国际机场钢屋架上弦主梁的残余应力进行现场测定。简要阐明了造成不同焊缝应力分布的原因及火工校弯成形工艺对构件残余应力分布的影响。
Residual stresses in girder of Pu-Dong international airport roof truss is measured by X-ray technique. The reasons for different mode of welding residual stress distribution and influence of flame curving on steel structure are discussed.
