A rectangular beam 250 mm wide, 500 mm deep is reinforced at the bottom with 4-20-mm-diameter bars and at the top
with 2-16-mm bars. Concrete cover to bar centroid at the top is 80 mm and at the bottom is 70 mm. Use concrete
strength f'c = 21 Pa and steel yield strength fy = 415 MPa for 20-mm bars and fy = 275 MPa for 16-mm bars
Determine the limiting tensile steel ratio for a tension controlled condition in positive or negative bending with the given material strengths.
4. An interior reinforced concrete slab has to be designed to support a live load and a
dead load in addition to its own weight based on the following specifications:
The slab is one-way and simply supported with a span of 12 ft.
The live load on the slab is 200 psf.
The dead load on the slab is 100 psf.
Your design will use concrete compressive strength fe= 3000 psi and steel
yield strength of fy = 40,000 psi
The 5-story building design project will
have its beams and slab poured
monolithically and formed a T- section as
shown. Determine the design strength
pMn in accordance with the ACI/NSCP
Code. The tension steel is 9- 36 mm
diameter bars (As of 36 mm = 1006 mm2)
with three bars in each of three layers.
Assume 12 mm stirrups are used, and
there is 25 mm between layers. Use fc':
28 MPa and fy = 413.70 MPa.
