This work concerns the stability of masonry piles with rectangular cross section, subjected to eccentric axial and lateral loads. The geometrical model is one-dimensional and the material is not withstanding tension. For the case of eccentric axial loads we set a limit to the material’s compressive strength and deformability. The differential equations obtained for the deformed shape of the most compressed fibre of the pile have been solved explicitly for every value of slenderness, initial eccentricity and slope of the acting load, and their solutions allow us to describe the stability characteristics of the pile through graphical representations. The values of the pile’s strength reduction factor, obtained for the case of eccentric axial loads, have been compared to those reported by some regulations.

Abstract
This work concerns the stability of masonry piles with rectangular cross section, subjected to eccentric axial and lateral loads.

The values of the pile’s strength reduction factor, obtained for the case of eccentric axial loads, have been compared to those reported by some regulations.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
