Abstract

Various forms of lack of fit may be experienced in the fabrication and erection of a steel structure. From a comprehensive survey of fabricators, consultants and local authorities, it was possible to identify the principal causes of lack of fit, especially where these resulted in disagreement. Guidance is given on the significance of various forms of geometrical imperfection. In particular the behaviour of friction grip and bearing bolt, and welded connections has been studied, together with overall frame fit problems. Advice is given on how to avoid lack of fit difficulties on site, by taking appropriate measures at the design and fabrication stages.
