WebAbstract: A simple equation is proposed for the stress-strain curve of concrete in compression. The equation is found to represent it well not only up to the maximum stress but also beyond, and may conveniently be adopted in the computa-tion of ultimate resisting moment of reinforced concrete sections. ALSO AVAILABLE IN: WebDec 30, 2013 · The size dependence of flexural properties of cement mortar and concrete beams is investigated. Bazant’s size effect law and modified size effect law by Kim and Eo give a very good fit to the flexural strength of both cement mortar and concrete. As observed in the test results, a strong size effect in flexural strength is found in cement … WebThe stress-strain curves of normal weight concretes of strengths up to 11,000 psi and lightweight concrete of strengths up to 8000 psi are reported. An analytic expression for the stress-strain curve of concrete is developed to reflect experimental results. The analytic expression has four constants which depend on the properties of both the ... cow wall calendar 2023
