. Details of riveted railroad truss bridges . Fig,38. A method where the gusset plate is used is shown in Pig, 38.

There may have been some object in view for thisdesign but it seems to be a poor one. One objection is theposition of the pin. In place of lacing in this bridge plates2-1/2 by 7/I6 were riveted at intervals along the lower sideof the end post. This design is simple but the appearance isanything but The Phoenix Bridge Company have designed a detail forthe connection of the end post to bottom chord. showsthis. The construction of this detail is simple enough. The twoplates which hold the end post and the top chord together alsosupport the end floor-beam. A serious objection to the design isfound in the fact that the pin is not in a line with the centreof gravity of the end post. As far as the construction is con-cerned this detail is good and makes a satisfactory connection. illustrates another neat detail employing agusset plate. This detail is good in that the pin is in line -25- with the centre of end post and bottom chord, and no bendingmoment can result in the connection. This detail is neat andevolves no difficulty of erection or design. The only draw backto this is the high pedestal that is required. shows a detail by a Montreal Bridge Company andwas designed for the Canadian Pacific Railroad. The peculiarity
