I need the answer immediately, please.
Problem 1: A singly reinforced rectangular beam has a
dimension b = 310mm and d = 410 mm. Factored moment
%3D
is equal to 300 kN-m, Concrete compressive strength is
24 MPa, Steel yield strength is 276 MPa and the reduction
factor is 0.9. Determine the required steel area in mm?.
Problem 2: A concrete one-way slab has a total thickness
of 120 mm. The slab will be reinforced with 10 mm
diameter reinforcing steel bars with fy = 276 MPa.
Concrete Strength f'c= 21 MPa. Determine the required
spacing of 10 mm RSB if the total factored moment acting
on 1-meter width of slab is 25 kN-m. Clear cover is 25mm.
Reduction factor is 0.9.
