rete abutment logically,divides itself into the following parts, first the determinationof the dimensions with reference to stability. Second the designof the vertical wall, and third the design of the footings. Sincethere should be no vertical tension in the footings, the resultantof the forces acting on the abutment must fall within the middlethird of the base. .Vith this in mind several trials were made andit was found that an abutment of dimensions shown in fig J? metwith these requirements. The problem therefore resolves itselfinto investigating this abutment for stability and proportioningthe steel. The vertical forces are the dead load weight of the bridge, the live load on the bridge and the weight of the abutments The loads coming to the abutment due to the dead load weight of one span of the bridge is equal to 2645 x 2 x 52 - 192,500. The load 2 coming to the abutment due to live load on the bridge is equal to85 x 16 x 52 - 26,000 making a total of 229,500 lbs. coming tc the

Since the abutment will be as long as the overall widthof the bridge or 18 - 8, the load per foot of abutment equals 829,500 - 12f£50 lbs The weight of the abutment acts at its center of gravitythe calculations for which are shown in the table. The weight ofthe earth back of the abutment acts at its center of gravity as isalso shown in the Table IV. Moments were taken about the lowerright hand edge of the footing.
