Abstract

Structural analysis for the restoration of the walls of Urbino G. Croci," M. Biritognolo/ V.M. Santoro^ & Department of Structural and Geotechnical Engineering, University of Rome, Italy ** Civil Engineers ABSTRACT The solution of many engineering problems are today found with the help of finite element models. The applications of this method assume, in general, an elastic behaviour for the finite elements. Where the real behaviour exceeds the elastic limit an alternative method must be adopted to take account of the non- linear behaviour. An example of the application of this method of structural analysis is found in the strengthening project of the walls of Urbino, based on an extensive investigation program concerning the soils, the foundations, and the masonry structures. The results of the survey have allowed a mathematical reconstruction of the wall's geometry and a simulation of the different patterns of failure that have occurred. INTRODUCTION The walls of
