Comparative Analysis of the Fink, Murphy, Bollman and Triangular Trusses Classic Reprint

Excerpt from Comparative Analysis of the Fink, Murphy, Bollman and Triangular Trusses Under the first and second heads we will then assume, that the Span of the truss is 200 feet, the depth 21 feet, and the width of floor from centre to centre of the trusses 18 feet. These dimensions are taken as a fair average between ordinary spans and those bolder reaches of greater length up to 300 feet, and even beyond, which are coming more into favor of late years. They are also the proportions of the iron bridge over Barren river, on the Louisville and Nashville Rail road, with the details of which the writer is familiar, he having been engaged on that road at the time of its erection.
