Masonry Vaults Behaviour

Abstract
Born as a method to design Strut and Tie Models in reinforced concrete
structures, the Load Path Method (LPM, Schlaich and Schafer [2], Vitone A. and
Vitone V. [3], Palmisano et al. [4]) has also become a simple and effective
instrument to understand the behaviour of masonry structures (De Tommasi et
al. [1]). This paper deals with the effectiveness of the application of the Load
Path Method to the diagnosis of the pathologies of the masonry vaults. While
proposing the principles and the general criterions of LPM for the case of the
arch, it will try to gather the correspondences with the classical approaches to
these themes. The method offers an interpretation of masonry vaults behaviour
that immediately exhibits the correlation among form (geometry) and structure
(distribution of loads and of thrusts): a particularly narrow correlation in the case
of the masonry vaults.
Keywords: masonry structures, arch, vault, strut and tie, load path.
1 Load Path Method: basic principles
The most suitable orthonormal Cartesian system of architectural forces to
physical environment in which they flow is the one capable of bringing them
back only to vertical loads and horizontal thrusts. According to this, structure can
be read as the trace of the loads path (De Tommasi et al. [1]). The form of the
structure is the result of their mutual integration and mainly of the influence of
profiles traced by the thrusts path, forced to deviate from their natural horizontal
Keywords
