A rigidez dos apoios na análise de flexibilidade de tubulações

The support structures of a piping system are, in lack of more accurate values, modelled as springs with high stiffness constants, for flexibility analysis purposes. Although one may justify this procedure based upon the conservative results which, usually, are obtained for the supports' estimated loads, its effects on the system's behaviour are not easily predictable. Stiffness values for some support structures are here investigated. In this context, the possibility of expressing the shape of supports of the vessel's nozzle kind by a reduced set of dimensionless parameters is exploired. A comparative case-stúdy of the behaviour of a system, when its suports are structurally modelled or, instead, an increasing sequence of stiffness constants is adopted, shows the need to obtain and employ values which can simulate more adequately the supports' actual stiffness.
