Question
A simply supported beam with a span
of 7.8 meters is subjected to a uniform
vertical load of 52 kN/m, acting on the
plane of the minor axis of the beam
section. The beam is restrained
against lateral buckling at the top and
bottom flanges for the entire span. The
material is A36 steel with Fy =248 MPa
and modulus of elasticity of 200 GPa.
The allowable flexural
stress for
laterally braced compact sections is
0.66FY.
Allowable shear stress is 0.40FY and
allowable deflection is 1/360 of the
span. Assume the section is compact.
Properties of steel section: Moment of
inertia, Ix = 0.00055 m, total depth, d =
533 mm, and thickness of web, tw = 10
mm., beam's wt = 90 kg/m
1. Compute the maximum bending
stress:
a. 194.87
c. 200.40
b. 154.32
d. 240.60
2. Compute the maximum deflection:
a. 23.17
C. 19.87
b. 15.60
d. 25.70
