The shear strength of reinforced concrete beams

Abstract.In this project the basic mechanism of resistance of reinforced concrete beams subjected to flexure and shear has been investigated.From an examination of the equilibrium conditions for the shear span of a beam it was shown that shear can be resisted in two different ways,namely by beam action and by arch action.The Strength of Chapter Concrete 3Chapter 3 3.1 The Importance of Strength 3.2 Strength Level Required KINDS OF STRENGTH 3.3 Compressive Strength 3.4 Flexural Strength 3.5 Tensile Strength 3.6 Shear,Torsion and Combined Stresses 3.7 Relationship of Test Strength to the Structure MEASUREMENT OF STRENGTH 3.8 Job-Molded Specimens 3.9 Testing of Hardened Concrete FACTORS AFFECTING STRENGTH 3.10Technical Specifications for Wedge AnchorsWelcome to Concrete Fastening Systems,Inc.!

Concrete Strength What is the Compressive Strength of Concrete? The strength of concrete is measure in terms of pounds per square inch (or PSI).PSI is a measure of compressive strength,or the ability of the material to carry loads and handle compression.1.) 2500-3000 PSI Most concrete has a PSI rating of 2500 to 3000.Square root of f'c for unreinforced concrete.
