'Detail of top member joint'

''Photograph of detail of top member joint. This picture is exclusively a detail one, and should therefore only be selected by those anxious to become familiar with the method adopted of connecting tubes and girders at their various junctions. The joint illustrated is junction of vertical column with top member, together with a strut and tie. Dimensions of the various members are given elsewhere. They are here represented by 4.3/4 in. 6 in. 3 in. and 7 respectively. The member is shown upside down, this being the position in which it was built in the yard.'' Transcription from: Philip Phillips, 'The Forth Railway Bridge', Edinburgh, 1890.
