This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1904 edition. Excerpt: ...or beams supported, and the unit pressure on the bottom of the plate. The material may be cast iron, wrought iron or steel; the unit pressure on the bottom of the plate is that used in finding the area of the plate (i. e., 5, 8, 15, or 18 tons per sq. ft., as above). DIAGRAM NO. 29 enables the required thickness to be readily obtained. The abscissas are amount of projection in inches. The ordinates are thickness of plate, there being three different ordinate scales, for cast iron, wrought iron and steel, respectively. Different diagonal lines represent the different allowable unit pressures on the supporting material. To use the diagram, take an abscissa equal to the projection of the plate, in inches, and follow up to the diagonal. The horizontal at the intersection gives, when followed to the right, the thickness of the plate. The clear distance between the inside flanges of a pair of beams must not exceed 2.45 times the projection of the plate beyond the outside flanges. For giving values for rivet requirements in connection angles, also areas for bearing plates. Diagram No. 29. For giving thickness of bearing plates of cast iron, wrought iron or steel. PROJECTION OF PLATES Note.--When the clear distance between the inside flanges of a pair of beams supported by a single plate exceeds 2.45 times the projection of the plate beyond the outside flanges, the thickness of the plate is to be obtained by the following modification of abscissa value for projection (not the real projection). Multiply the clear inside distance between flanges by 0.41 and use this value on the abscissa scale. Part HI.--Columns and Truss Members. CHAPTER VII.--STEEL COLUMNS. The usual methods of designing built steel columns are either quite complex or else they apply to...show more
