摘要
以变形观测的方法对钢结构网架工程在设计荷载作用前、后的挠度进行测量,并以某大型钢结构网架屋面工程挠度测量为例,利用S1型精密水准仪分别对网架自重及网架屋面工程完成后进行挠度测量验算,以满足规范要求,并对应用水准仪进行大型钢结构网架屋面工程挠度测量的方法及精度进行探讨。
The deflection is surveyed using deformation observation method to steel structure net rack engineering before and after design loading action. Taking the large steel structure net rack roofing engineering for example, authors survey net rack tare weight and roofing engineering deflection and make check computation using S~ level, to satisfy norm requirement, discuss the deflection survey method and precision of large steel net rack deflection.
