Design a rectangular section for the following beam considering the given loading. The weight of the beam is included in the given loading. Use pmax such that will not be less than 0.9. Show sketch of cross section including bar sizes, arrangement, and spacing. Verify that the bar layout will fit within the width of the selected beam cross section. Verify that the selected bars will not exceed the targeted reinforcing ratio (pmax). Assume normal weight concrete that weighs 150 pcf, fy = 60,000 psi, and fc' = 4000 psi. 10' PL = 35 kips WD = 2.5 k/ft 101-

What is the value of the Whitney stress block parameter, β1β1, for 6000 psi concrete?

Correctly define which of the stress versus strain graphs represent the comparison of 8 ksi and 4 ksi concrete for the chart below (say left or right). Qualitatively compare the w/c ratio, elastic modulus, and brittleness. 0.000 0.003 0.000 0.003 Sean, e Sane Feure 2 Strss vesus Srain curves Feure 2. Stress vasus rain curve
