Abstract

It is demonstrated which methods of modern FEM calculations can be employed to analyze the stability of pressure-injected composite piles for the purpose of reinforcing masonry. The interaction between composite piles and masonry is taken into consideration. The linear-elastic bifurcation loads are determined The physically and geometrically non-linear load increment problem is investigated. 1 Introduction Masonry is a very complex material from the point of view of providing static proof The compound is inhomogenous, anisotropic and non-linear If proof is required with regard to the limit state of strength and stability, German standards always refer to some individual aspects of this complexity [1], which are not always consistent. In case of complex problems, the planning engineer is often faced with the
