Page 946 - At the ends of compression members the pitch shall not exceed four diameters of the rivet, for a length equal to twice the width of the member.
Page 649 - The bending moment at any point of a beam is the algebraic sum of the moments of all of the forces (the reaction included) acting upon the beam, on either side of that point, the point being considered as the center of moments. The expression "algebraic sum...
Page 859 - Plate girders shall be proportioned upon the supposition that the bending or chord strains are resisted entirely by the upper and lower flanges, and that the shearing or web strains are resisted entirely by the web plate; no part of the web plate shall be estimated as flange area. The distance between centers of gravity of the flange areas will be considered as the effective depth of all girders.
Page 898 - The pitch of rivets at the ends of built compression members shall not exceed four diameters of the rivets for a length equal to 1^ times the maximum width of the member. (d) Two-Angle Members. In tension members composed of two angles, a pitch of 3'-6...
Page 816 - The attachment of the lateral system to the chords shall be thoroughly efficient. If connected to suspended floor beams the latter shall be stayed against all motion.
Page 1014 - ... running between planed surfaces. The rollers shall not be less than 2 inches diameter, and shall be so proportioned that the pressure per lineal inch of rollers shall...
Page 674 - Table 30, and / = least moment of inertia of the cross-section — that is, the moment of inertia about an axis passing through the center of gravity of the cross-section and parallel to the longest side. In other words, if the...
Page 897 - Preference will be had for such details as shall be most accessible for inspection, cleaning and painting; no closed sections will be allowed.
Page 889 - M = — , (12) c in which / represents the moment of inertia of the beams crosssection, and c the distance from the center of gravity of the section to the outermost fiber.
Page 663 - ... strains are directly proportional to the horizontal stresses in each fiber, they are also directly proportional to their distances from the neutral surface, provided the elastic limit is not exceeded.
