  • Why should steel fail(yield) first before the concrete in

    So we generally don't depend on concrete in tension, and cracking is not considered 'failing'. Crushing, on the other hand, does amount to failure. In bending elements, we want the ultimate failure mechanism to be yielding of steel rather than crushing of concrete, as that is a much more ductile failure mode.,
