thickness tG (in
mm).
You should assume all corners are perfectly square.
The RHS is made from steel (Es = 200000
MPa), and is filled with concrete (Ec =
25000 MPa). You should assume both materials exhibit linear elastic
behaviour. The concrete cracks in tension at 5.75 MPa.
The RHS is used as a beam, bending about
the horizontal axis.
Part G
dG = 140 mm
tG = 4 mm
Now consider a different bending moment that creates a maximum
tension stress of 15 MPa in the steel.
What is the maximum tensile strain (in microstrain) in the
concrete?
