To quickly assess the difficulty of the text, read a short excerpt:
At all floors from the second to the roof, one^half of the floor 35. load is transmitted to the column through the girder. The girder is conreoted to the wet of the oolumns and the load is considered as concentric. The spandrel beams which transfer the wall loads ere connected to the outside of the column and, therefore, causes eccentric loads. The formul We = V/' eo is used for the determin- r' atlon of this eccentricity. r2 The calculations. the floor aree tributary to the exterior columns is... 229.6 _ 164.75 souare feet. 2 the total floor dead load equals 164.75 X 88 - 14,495# the wall being of terra-cotta, filled and backed with brick, the weight is taken at 120# per cubic foot, the wall load minus the window area is (4.25 X 17,5) (6.0 x 7.4) x 1.2 x 120 - 118.77 X 1S2 = 15780# the weight per column is taken as given for the inter- ior column = b9bO$ 36. Eccentric effect. The spandrel load and one-lialf of the floor dead load is eccentric. spandrel load s I5,780# i floor d.l. . 7,250# eccentric load =23,000# the eccentric effect is, therefore, 25000 x 8x 6 2.60 X 2.60 = I26,275#.
