The Tyne Bridge (1928): A General Description of its Construction and a few Comparisons with the Sydney Harbour Bridge

TENSION members in a structure are of definite and known strength, if the grade of the steel be known. The strength in a test can be predicted with small error. Edward Godfrey

The assessment suggested in these tables is an endeavour to crystallise the general ideas on which the writer has found practical designers to have worked in the past, and he has attempted to expand them on the basis of the L.C.C. Code of Practice in the hope that they will give some stimulus to discussion on the part of those designers who have to sort out the rather elaborate but necessary specification of restraints given in the Code, and award them to suitable construction. G.F. Rodmell

THE following notes and observations are intended to apply to such bridges as may be built by Local Authorities, designed by their engineer, and erected possibly by direct labour. It will later be evident that the subject has been viewed from the experience acquired principally in the past ten years in building fifty or sixty bridges and applies to spans up to and including about 120 ft.
