Document Type: Journal Paper


The concept of the pressure line, useful for arches and rigid frames, is developed for quickly estimating the effects of plasticity on the behavior of structural elements subjected to axial and flexural loads. An initial estimate, obtained by means of an elementary theory of mechanics, is adjusted to fit the conditions of plasticity.
