Thanks for all your replies...
@desertfox, I agree that adding steel to the inside is a waste. Thanks for the link!
To get a rough estimate, I multiplied the Inertia of the steel section by 3 (with E of steel being 3 times larger then that of aluminium) and just calculated the deflection...
Hi there
I need to calculate the maximum bending moment for an aluminium section which has two steel flat bars fixed inside the section. I know how to calculate the Mu for the aluminium and steel section separately. I was wondering if it possible to just superimpose the two Mu's onto each other...
Hi
I am calculating the ultimate limit state of a aluminium section using AS1644.1 clause 3.4.13. I need to find Rb/t with Rb = mid-thickness radius of curvature of curved plate and tubular beam elements and t = thickness. Below is the section I need to calculate...
