As considerable weight and shock comeson the end floor-beam, it is necessary to extend a gusset plateabove the intersection of the bottom chord and end post to makea solid connectoin. ITo serious objection can be seen to thisconnection. The American Bridge Company use a simple means offastening the floor-beam. This consists of letting the lowerflange of the floor-beam rest on the bearings and plate is then riveted to the floor-beam and bent so as to -11- fasten on the cover plate of the end post in order to stiffenthe floor-lDeam and keep it from rotating about its lower detail is shown in Fig, ooooooooooo ooooooooooo There is little question but that this detail is themost of end floor-beam connections on account of itsease in putting in place and the absence of many field appearance may not be as neat as some others but is as effect-ive and is also more economical. Ij A similar detail to this is where the plate is rivetedto the side of the end post instead of the top. It is difficultto rivet this plate to the side on account of the flange andproximity of the floor-beam itself. A Canadian bridge company used a detail as sho^n The upper flange and part of the web of the floor-beam is allowed to extend over the top of the end post. Theend post has flanges on either side and in order to place the -12- floor-lDearn in place a portion of each flange is removed. Aplate is riveted to the end post and floor-bean to prevent arotating about the intersection of the web and end post. Allthe stress is transfered through rivets to the end post. The
