GUI G 3 Structural action in steel box girders

Publication Year

1977

Document Status

Amber 
Caution

Abstract

A discussion of linear elastic analysis of box girders shows how it can be used to determine shear lag, torsional warping, stresses due to distortion, stresses in multi-box systems, and the limits of elastic behaviour. Next, elastic buckling and post-buckling of plates, caused by longitudinal compression and shear, are dealt with. The determination of buckling strength of panels and webs stiffened by flange plates is explained. Stress distribution in bearing diaphragms is discussed, and the reasons for failure are given. Secondary stresses caused by interaction between flanges and diaphragms, and due to restraint of warping, are explained. The effect of imperfections and residual welding stresses is discussed. Finally, general considerations in applying structural analysis to design in relation to the Merrison Rules are presented.

Document Status Indicators

Green The Green document status indicator indicates that the document is:
  • (a) current in the Construction Information Service and
  • (b) the latest version - ie it does not have any other documents that replace or amend it and is promoted as a current document by the publisher.
Amber The Amber document status indicator indicates that some caution is needed when using this document - it is either:
  • (a) current in the Construction Information Service but has a document or documents that replace or amend it, so please look at the "Newer Versions" tab or
  • (b) not in the Construction Information Service but with another reason why it may be relevant to our customers such as being cited in NBS or in the Building Regulations Approved Documents. Again there may be more recent versions of the document.
Red The Red document status indicator indicates that the document is an old version
  • The document has likely been withdrawn by the publisher, also the meta data presented here may be out of date as it is no longer being maintained by the editorial teams at NBS.
