Unformatted text preview: to a constant normal compression stress in the axial direction of 120 psi. The panel is then subjected to a uniform shear stress v (while holding the axial stress constant). Using the Modified Compression Field Theory, estimate the average shear stress v and average shear strain γ values at first cracking and first yielding of reinforcement. 14” 24” 8 #8 long. Bars #4 at 4 in. hoops Cover to bar centroid = 2.5” (on all sides) Material properties: Concrete: f’ c = 5000 psi; ε co = 0.002; Steel (assume elastic perfectly plastic response): f y = 65 ksi; E = 29,000 ksi...
