摘要
通过起拱方式与网架挠度曲面的比较,指出了不同跨度网架的合理的起拱方式,并讨论了施工起拱对网架内力状况和使用阶段的影响。
Through the contrast between the cambering mode and the deflection curve surface of the grid - truss, this paper points out the proper cambering modes of different grid - trusses as well as the effects of cambering in construction on the internal forces and stages of use of the grid - truss.
