Formula-se o problema de custo mínimo de secções rectangulares de betão armado à flexão segundo o Eurocode 2 nas variáveis de dimensionamento altura de secção e àrea das armaduras. As condições de optimalidade de Khun-Tucker sao resolvidas simbolicamente, obtendo-se 6 soluções de armadura simples com rotura pelo betão, pelo aço e simultânea, e uma solução de armadura dupla com rotura pelo betão. Identificamse as regiões de optimalidade, que se mostra serem adjacentes, de cada uma das soluções no plano Cartesiano dos parâmetros "momento adimensional" - "rácio das eficiências económicas do betão e do açoThe minimal cost problem of rectangular reinforced concrete sections in bending according to Eurocode 2 in the design variables section heig...
