Question

A one-way solid slab of a span of 3000 mm and a total thickness,
f is 414 MPa, the total cover of steel is 30
mm, minimum reinforcement ratio is _{y} ,ρ =
0.0033, maximum reinforcement ratio is
_{min}ρ = 0.0135, and density of concrete
_{max}γ = 24 kN/m_{c}^{3}. What is the required
area of steel reinforcement, A, needed to
resist the ultimate bending moment? urgent answer please_{s,req.} |

Answer #1

Area of steel required to resist moment developed is calculated.

Calculated area of steel is checked for minimum and maximum steel ratio.

Knowing that the reinforced concrete beam cross section
effective depth is d = 310 mm and the properties of materials used
are f'c = 28 MPa and fy = 420MPa and the external ultimate bending
moment Mu = 254 KN.m with strain in tension steel reinforcement
equal to 0.005 . The width of the beam is Select one : a . 511 b .
385 c . 460 mm d . 640

The project will include the design of One Way Slabs, Beams and
Columns.
Choose the largest room in your house/apartment and measure the
area. let's say (length 6m* width 4m) ( height 3m)
Steel yield stress (fy = 60000 psi)
Concrete ultimate compressive strength (f’c = 4000 psi)
Reinforced concrete density = 150 lb/ft3.
Normal weight concrete is used.
The slab is treated as a one way slab and subjected to a dead
load of 120 psf (excluding the self-weight...
