Masonry Vault Behaviour

Abstract
Born as a method to design Strut and Tie Models in reinforced concrete
structures, the Load Path Method (LPM, Schlaich and Schafer, Vitone A. and
Vitone V., Palmisano et al.) has also become a simple and effective instrument to
understand the behaviour of masonry structures (De Tommasi et al.). 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 vault 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 to bring back them
only to vertical loads and horizontal thrusts. According to this, structure can be
read as the trace of 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 thrusts path, forced to deviate their natural horizontal flows to the soil,
Keywords
