SITUATION: A simply supported beam has a span of 12 m. It carries a total uniformly distributed load of 21.5 kN/m. To prevent excessive deflection, a support is added at midspan.
Properties of steel beam
Area = 8530 mm2 Flange thickness = 14.6 mm
Depth = 396 mm Ix = 145 x 106 mm4
Flange width = 204 mm E = 200,000 MPa
Web thickness = 8.5 mm
1. Calculate the reaction (kN) at the added support.
A. 161.25 C. 108.60
B. 125.50 D. 172.85

2. Calculate the resulting moment (kN-m) at the added support.
A. 96.75 C. 102.36
B. 88.50 D. 145.25

3. Calculate the resulting the maximum positive moment (kN-m).
A. 81.86 C. 62.24
B. 42.05 D. 54.42
