A related problem of some significance which to date has not been studied in great detail is the response to service loads of steel-concrete composite beam with web openings. The problem would appear to be solved using standard assumptions of elastic behavior of a transformed section. Such is indeed the case if the concrete is not cracked. However, consideration of a cracked section in conjunction with application of Vierendeel method of analysis leads to which a closed form solution does not appear possible. The purpose of this note is to present the formulation and solution algorithm for this problem.
