4.9-7 Two plates 916 × 10 are welded to a W10 × 49 to form a built-up sha shown in Figure P4.9-7. Assume that the components are connecte the cross section is fully effective. F-50 ks, and KxL-Kyl-25 ted so that ft. FIGURE P49.7

Solution

As it is not mentioned what is to be determined.

If you want to know whether it can be used or not?

Yes,it can be used effectively if we make the welded connection strong enough to resist shear as well as in tension.Although welded connection are weak in shear so weld size and check should be provided according to shear.and also these plates enhance the property of the section.

If you want to know section strength in bending it can be done by calculating the section modulus and multiplied with bending stress.
