SITUATION. The design of a beam yields the following:
h1 = 110 mm
h2 = 490 mm
b = 375 mm
As '=3 of 28 mm diameter bars
As 5 of 28 mm diameter bars
Concrete compressive strength, fc' = 34 MPa
Longitudinal steel yield strength, fyl = 413 MPa
Lateral ties yield strength, fyv = 275 MPa
Effective Cover to the centroid of As = 75 mm
Shear strength reduction factor = 0.75
