A rectangular plain concrete beam section, 250x500 gross dimension, is cast using a concrete strength fc’ = 30 MPa. Assuming the concrete to crack at a tensile stress equal to 3.28 MPa, determine the magnitude of a concentrated load, excluding its own weight, at midspan that the beam can carry before it cracks if it is on a simple span of 5 m.
Concrete weighs 24 kN/m3.
Use Mmax=wL/4.
Determine the LRFD moment capacity (φbMn) of a composite section that is comprised of a W30x99 with a 5-inch, (f’c = 4 ksi) slab on top of it. The beam span is 30-ft and the spacing of the beams is 8-ft. Show all work. Determine how many 3/4-inch shear studs would be required to ensure that this section is fully composite.
