. Describe the response of concrete subjected to cyclic loading with the help of a graph. (Note: Please plot a graph and then describe the effect of cyclic loading on strength and modulus of elasticity of concrete. You will not get credit if you cut and paste the graph from class notes). 2. Discuss why testing of concrete for direct tensile strength is difficult to achieve. What indirect test methods have been developed to assess the tensile strength of concrete?...
Qu estion 1: (25 points) The beam shown below has a span of 13 ft and is reinforced with bars that ext end 8 inch beyond the face of the support. The centerline of the longitudinal bars nearest the side ace (i.e., the "outside bars") is 3.5 inch from, the side face as shown below. The concrete has a compressive strength of 3.0 ksi, and the reinforcement is Grade 60. The beam is loaded with a distributed live load (w)...
Fill in the blanks (20%) res in materials help to improve heat insulation or sound adsorption. Generally the materials with more pores possessed better heat insulation. res showed better sound adsorption. (open or Those materials with more close) 12 For the brittle material, few deformation appears before fracture, and by the brittle material often fractured suddenly without any premonition. For the brittle L, the compressive strength usually much than tensile strength. in silicate minerals in the cement clinkers are, and...

for problem 6.20, please help me understand how they come up
with those numbers for the area: A=(9x12-3x3)/5 ???
and how is Cc = (3-0.564) ??
ans how is fs = (0.67x60000) ??
explain how they come up with those numbers for Area, Cc, and
fs, please, thank you!!
