Abstract:

The rule of full stress is an efficient method in the optimal design for statically indeterminate shape steel truss. But the major shortcoming of this method is that the convergent speed is very slow. In this paper, a new area ratio method for the optimal design based on full stress is proposed on the basis of "the direct method of stability design for shape steel columns", in which the convergent speed of repeated calculations is greatly improved, and the design cost is effectively reduced.
