Standard Specifications for Structural Steel - Timber - Concrete and Reinforced Concrete

Standard Specifications For Structural Steel - Timber - Concrete And Reinforced Concrete by John C. Ostrup. This authoritative reference compiles early 20th-century design standards for the structural materials used in civil engineering. The work covers the complete range of structural specifications: steel frameworks for buildings, highway and railroad bridges, plate girders, and the general Materials and Workmanship provisions; inspection, painting, and erection; structural timber; cement and Portland cement concrete; and reinforced concrete. It lays out allowable stresses for axial tension and compression, bending, shear, and bearing, as well as dead loads, snow, wind, crane loads, and impact factors. The text details jointing and riveted connections, rivet sizes and pitches, tie plates, web stiffeners, expansion rollers, and bearing provisions. It also provides guidance on forms, placing of reinforcement, curing, waterproofing, fireproofing, expansion joints, and construction joints, plus detailed rules for timber quality and road and rail bridge design. Published originally in 1911 by McGraw-Hill, this edition reflects the era’s evolving understanding of structural efficiency, safety, and economy.
