ACI SP-50:1975 PDF Download

The ACI SP-50:1975 standard presents papers that address current issues for concrete research and design professionals, specifically those related to problems encountered in the application of the 1971 ACI Building Code. The standard covers a range of topics, including the re-examination of the "EI" value for slender columns, the effect of yielding of restraints on slender concrete columns, repeated loading tests of reinforced concrete columns, and the ultimate strength of biaxially eccentrically loaded concrete columns reinforced with high strength steel.

Other papers in the standard discuss the behavior of reinforced concrete columns in flat plate structures, the design of symmetric square slender reinforced concrete columns under biaxially eccentric loads, slenderness effects in reinforced concrete square columns, and the use of rectangular ties in reinforced concrete columns. Additionally, the standard includes papers on the analysis of restrained reinforced concrete columns under biaxial bending, the simplification of biaxial bending, the effect of axial load on the moment-curvature relationship of reinforced concrete members, and the axial load-moment-curvature characteristics of prestressed concrete members.
