Dilatational Effects in Nonmonolithic Structures

  • H. Parland

Abstract

The structural analysis of reinforced concrete structures and stone structures has been based on a continuum-mechanical treatment adopted from monolithic structures such as steel structures. The nonlinear discontinuous effects induced by cracks and dry joints have been smeared out and interpreted as softening material nonlinearities. Reinforced concrete and stone structures being nonmonolithic remain in working condition inspite of the gaps and cracks still in the elastic stage where the reversibility of displacements is preserved. In their elastic stage the effect of displacement discontinuities on the internal equilibrium is more pronounced. Because of the impenetrability condition they induce strong dilatational effects which discontinuously change the internal equilibrium.
