Texas A&M University Zachry Department of Civil Engineering CVEN 444 Structural Concrete Design Fall 2010 Date Assigned: Tuesday, September 14, 2010 Date Due: Tuesday, September 21, 2010 Assignment No. 2 (100 pts.) 1. From basic mechanics (CVEN 305), provide the expressions for computing the normal stress and shear stress for a beam in bending (assuming elastic behavior). State other assumptions in these expressions. Define each of the variables and include any additional expressions needed to

Unformatted text preview: describe how the variables are computed. Show both stresses for a typical beam section over the beam depth. 2. Text problem 3-5 3. Define shrinkage and complete text problem 3-6 4. Define creep and complete text problem 3-7 5. Draw a typical stress versus strain diagram for normal strength concrete (4 ksi < f’c < 8 ksi) and label the key points. 6. Draw a typical stress versus strain diagram for Gr. 60 reinforcing steel and label the key points....
