“…In this respect, starting from the seminal work of Kooharian (1952), the individuals which gave the more important contribution to this rediscovering were Jacques Heyman with a series of works originating from the seminal paper (Heyman, 1966) of 1966, whose title is 'The stone skeleton' (and later, with the monography (Heyman, 1995) by the same title), and Santiago Huerta, with a number of works originating from his doctoral thesis of 1992, and among which the cutting paper (Huerta, 2006) by the provoking title "Galileo was wrong", stands out. The main message of Heyman's theory is that masonry structures are essentially unilateral and that the theorems of limit analysis can be used to assess their stability, as remarked in Livesley (1978), Como (1992), Angelillo (2014Angelillo ( , 2015; Brandonisio et al (2013Brandonisio et al ( , 2015Brandonisio et al ( , 2017, , Angelillo et al (2014), Fortunato et al (2015Fortunato et al ( , 2018 and Portioli et al (2014).…”

Masonry structural modelling needs of a completely different methodology from the ones adopted for ductile structures. In fact, the concepts of strength, stiffness and elastic stability, fundamental for the latter structures, play a marginal role in masonry mechanics. In this respect, Heyman's theory, gives a modern turn to the old methods of masonry design, adopting a set of very simple and clear mechanical hypotheses. In these papers, the basic ingredients of a new method based on unilateral equilibrium and rigid block kinematics, which may allow the implementation of Heyman's model for masonry on a computer, is introduced. In particular a simple method based on energy minimisation, with the possibility of combining the effects of loads and settlements on real masonry structures, is developed.

“…It is known that old masonry often features nearly zero tensile strength [1,2,3]. Nowadays, it is a common practice to reinforce such structures by applying tensile reinforcements made of traditional materials, such as steel, or innovative high-strength materials [4,5,6].…”

Abstract. We present a discrete element model of a masonry structure strengthened through the application of reinforcing elements designed to work in tension. We describe the reinforced masonry structure as a tensegrity network of masonry rods, mainly working in compression, and tension elements corresponding to fiber-reinforced composite reinforcements, which are assumed to behave as elastic-perfectly-plastic members. We optimize a background structure connecting each node of the discrete model of the structure with all the neighbors lying inside a sphere of prescribed radius, in order to determine a minimal mass resisting structure under the given loading conditions and prescribed yielding constraints. Fiber-reinforced composite reinforcements can be naturally replaced by any other reinforcements that are strong in tension (e.g., timber or steel beams/ties). Some numerical examples illustrate the potential of the proposed strategy in designing tensile reinforcements of a three-dimensional structure composed of a masonry vault and supporting walls.

In this paper the lower bound theorem of limit analysis for No-Tension materials is applied to the equilibrium of spiral vaults, modeled as continuous unilateral membranes. The most efficient approach to the equilibrium of a thin shell is the covariant representation proposed by Pucher and adopted in the present study. Statically admissible singular stresses in the form of line or surface Dirac deltas and lying inside the masonry, are taken into account. The unilateral restrictions require that the Airy stress function representing the stress, be concave. The case study is a helical stair with a central pillar in Sanfelice Palace in Naples, whose structure is a tuff masonry spiral vault. The maps of the stress corresponding to two different stress functions and the safety factors in the two cases are provided
