Unformatted text preview: Behavior of Concrete under Various Stress States 1. Describe the stress-strain behavior of concrete under (A) uniaxial compression, (B) uniaxial tension, (C) biaxial compressive stresses, (D) biaxial tensile stresses, and (E) combined tension-compression biaxial stresses. 2. What is the relationship between shear strength and compressive strength of concrete? Elastic Moduli of Concrete 1. Describe the meaning of the following elastic moduli and how they are determined: (A) Secant modulus (B) Tangent modulus (C) Chord modulus (D) Dynamic modulus 2. Describe how the elastic modulus is determined in the standard test for static modulus of elasticity (ASTM C469). Which modulus was determined? 3. Describe the effects of the following factors on the elastic modulus of concrete: (A) Moisture condition (B) Aggregate properties (C) Properties of hydrated cement paste (D) Properties of transition zone...
