A simply supported steel beam has a span of 6m. and is
subjected to a vertical concentrated load of 150 kN acting
at midspan. An allowance of 100% for impact is made for
the concentrated load only. The beam is laterally supported
only at the supports. The 1992 National Structural Code of
the Philippines States that the allowable tensile stress for
laterally unsupported members subject to bending is 0.60
Fy while the allowable compressive stress for laterally
unsupported members subject to bending is given by the equation.
Where Cb maybe taken as 1.0 since the maximum moment
does not occur at the supports, rt is the radius of the
compression web area, taken about the axis in the plane of the web.
