r and method of attachment as was shown in Fig. 266. Fig. 268 shows the cross-section of two styles of through plate girder bridge in which the ironfloor system shown in Fig. 267 is dispensed with and the track supported on large cross-ties rest-ing on shelf-angles riveted to the webs of the… … Fig. 26g. The iron weights of the various styles of plate girder bridges * may be approximated bythe following formulae: Deck Plate Girder Bridge, w = gl -\- \ \o\ Through Plate Girder Bridge, w — 8f / -|- 300 (iron floor system); w = g\l -\- 150 (large ties on shelf or flange angles); w = 10/ -|-…
