A fully-restrained beam with span length of 10 meters was designed using ASTM A36 steel (Fy = 250 MPa) rolled as W16x57 section. Lateral bracing was only provided on the supports and on third points. The said beam is to be subjected to a super-imposed uniformly distributed dead load of 5.00 kN/m and a total uniformly distributed live load of 20.00 kN/m. The only deflection limit imposed for the design of the said structure is that its deflection at midspan due to total service loads should not exceed its span length divided by 150. Assess if the designed section for the beam is adequate for its purpose. Consider flexure, shear, and the imposed deflection limit. Use ASD specifications. Assume unstiffened webs.

A fully-restrained beam with span length
of 10 meters was designed using ASTM
A36 steel (Fy = 250 MPa) rolled as
%3D
W16x57 section. Lateral bracing was
only provided on the supports and on
third points. The said beam is to be
subjected to a super-imposed uniformly
distributed dead load of 5.00 kN/m and a
total uniformly distributed live load of
20.00 kN/m. The only deflection limit
imposed for the design of the said
structure is that its deflection at midspan
due to total service loads should not
exceed its span length divided by 150.
Assess if the designed section for the
beam is adequate for its purpose.
Consider flexure, shear, and the imposed
deflection limit. Use ASD specifications.
Assume unstiffened webs.
