The optimal design of reinforced concrete folded plate structures under multiple loading conditions is presented. The design variables include geometrical quantities, like the thickness, dimensions of the structural members (plates), and topological parameters, which define the locations and the connectivity of such elements. The structural analysis required during the design process is performed by using the classical finite strip method and complex harmonic coupled finite strip method for the solution of the corresponding geometric non-linear design problem. Some applications to the optimal design of prismatic folded plates show the effectiveness of the proposed procedures.
Key words: finite strip method, folded plate structures, reinforced concrete.

OPTIMALNO PROJEKTOVANJE ARMIRANOBETONSKIH POLIEDARSKIH LJUSKI MODELIRANJEM METODOM KONAČNIH TRAKA Prikazano je optimalno projektovanje armiranobetonskih poliedarskih ljuski za složene uslove opterećenja. Projektne promenjive uključuju geometrijske veličine kao što su debljine, dimenzije strukturalnih elemenata (ploča) i topološke parametre koji definišu položaj i povezanost elemenata. Proračunska analiza je izvršena primenom klasičnog i kompleksnog harmonijski spojenog metoda konačnih traka za rešavanje odgovarajućeg geometrijski nelinearnog problema. Efikasnost predloženih procedura je pokazana na primeru optimalnog projektovanja prizmatičnih poliedarskih ljuski.
