A steel beam, of lengths a= 4 m and b=4 m and
a hollow box cross section, is supported by a
hinge support A and roller support B, see Figure
Q.1. The width and height of the cross section
are 200 mm and 300 mm, respectively, and the
wall thickness of the cross section is 5 mm. The
beam is under a distributed load of the intensity
that linearly varies from q = 0 kN/m to q = 4.2
kN/m for AB span; and is constant with q = 4.2
kN/m for BC span. The Young's modulus of steel
is 200 GPa.
