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.
750 mm
T175 mm
1000 mm
9-36 mm diameter bars

Given the section and plan view of the structural elements (Foundation and Column), estimate the concrete material quantities to be used in construction. There are sixteen (16) - C3F2 in the entire structure. Consider only from the foundation base up to the Natural Ground Level (NGL). The concrete is to have a minimum compressive strength of 3500 psi (24 Mpa).
