I need a solution for this advanced mechanics of steel structure problem: A composite beam of rectangular cross section is constructed by joining material “A” with material “B": material “A” is joined to material “B” in such a manner so that fully composite behavior is achieved, i.e plane sections remain plane over the entire cross section. Material "A" Material “B” Given: Material "A" and "B" are both elastic -perfectly plastic, with the following properties: Material "A": E = 30,000 ksi and...
