It is never satisfactory to design a structure piecemeal. The whole construction ought to be considered as one unit and designed from the outset to meet each of the several loading actions to which it may be subjected. Part structures designed for one principal loading system and later modified to accord with other part structures or to meet other loading requirements, will seldom prove efficient. Moreover a structure designed from the outset to meet alternative loading cases is necessarily better integrated than a structure designed primarily for one loading case and later modified to meet another.
