Abstract:This paper provides a new method to design the optimal shape of 2D frame structures even (or especially) if not statically determined. The optimization here addressed involves obtaining the uniform strength of the whole structure, but the proposed procedure can be followed for other optimization goals. Two types of beam cross-sections are studied, in which the solution in terms of balance, kinematic and beam-shape is found analytically and involves six unknowns for every beam element. For frame structures, som… Show more
