Abstract:

The paper discusses minimum-weight design of beams of continuously varying cross section that have to carry any one of n systems of loads. The weight per unit length is assumed to be given by wx a bYx, where a and b are constants and Yx is the yield moment at the cross section x. A design method is presented that remains valid for the extreme cases n 1 and n infinity and that enables the designer to prescribe a minimum value Y sub o below which the yield moment is not allowed to drop. The use of the method is illustrated by examples. Author
