Question

Q Given table displays the bending moments and shear force values for beam B2 at the supports and midspan.
Beam B2: Clear span, 28 inches wide by 33 inches deep, l_n = 25.17, f_c' = 4000 psi, f_x = 60000 g.
In B2, there is hardly any axial force. Required. Frame Beam B2's schematic design and detail using the provisions of ACI 318-99.

1. U = 1.4D + 1.7L
2. U = 1.2D+F₁L + 1.0E,
where E = PQE+ 0.2SDSD
Since F₁ = 0.5, p = 1.0, and
Sps = 1.0,
U=1.2D +0.5L + QE+0.2D
= 1.4D + 0.5L + QE
3. U=0.9D-1.0E
= 0.9D+PQ-0.2SpsD
U=0.7D+QE
