The Structural Engineer, Volume 10, Issue 11, 1932
0N pages 355 to 363 in the August Number of The Structural Engineer was published a short article "On a new method for the practical use of Modern Pillar Formulae." The suggested method involved the use of two Tables of constants, Tables Nos. 1 and 2, which were given on pages 357 and 359, respectively. For the sake of brevity these Tables were calculated for ratios of l/g at intervals of 5 together with the differences to enable the intermediate values to be determined. W. Cyril Cocking
THE work which forms the subject of this paper can most conveniently be considered as two distinct undertakings, namely, the reconstruction of the Pier Head and the provision of a new approach viaduct supporting an additional line of way, with reconstruction of existing platforms adjacent thereto.
