Description

It is important, for safety reasons, to determine the actual behaviour and to estimate the features required for reinforced concrete structures in nuclear reactors, subjected to accidental loading such as impacts or earthquakes. Moreover it is preferable for economic reasons to work out global laws with a computer programme using global concepts. Such methods have already been proposed for elasto-plastic materials and for loadings which are predominantly bending loads with a relatively weak normal force component. This paper proposes an extension of these models to include any value of the normal force and considering non-simplified behaviour laws for concrete and steels. The formulation is of elastic-damage-plastic type. (author)

Abstract (Portuguese)

A determinacao do comportamento de estruturas em betao armado, fazendo parte integrante de instalacoes nucleares, assume particular importancia, em seguranca nuclear, quando se pretende avaliar a sua resistencia em presenca de carregamentos acidentais como impactos ou sismos. Por razoes de ordem economica, e preferivel desenvolver uma formulacao global. Tais metodos foram ja propostos, admitindo um comportamento elasto-plastico para os materiais e carregamentos dominados pela flexao, considerando uma componente de esforco normal pouco importante. Nesta comunicacao e apresentada uma extensao dos modelos precedentes, por forma a incluir qualquer valor de esforco normal e considerando leis de comportamento real para o betao e os acos. Foi adotada uma formulacao global elastica-linear, de dano e plastica. (autor)
