Recent developments in the quality and accuracy of additive manufacturing have drawn particular attention to metamaterials characterized by a multistable response achieve exceptional mechanical properties. This work focuses on design, fabrication, testing, simulation tensegrity-like lattice chains accomplishing behaviour. The are composed chiral units featuring highly nonlinear bistable with compression-twisting coupling. Different designed exploiting chirality realised inverted...
Abstract The mechanical response of additively-manufactured hollow truss lattices is experimentally investigated under quasi-static compression testing. Exploiting the recent developments in Fusing Deposition Modelling (FDM) technique, two families have been fabricated, obtained as tessellation space octet-truss and diamond unit cells. Four specimens for each family designed with prescribed relative density, selecting different inner-to-outer radius ratios r/R their struts. Compression...
The results of multidisciplinary research carried out on the Byzantine Stylite Tower in Umm ar-Rasas archaeological site (Jordan) are presented this paper. study is grounded precarious structural conditions tower, assessed by UNESCO since 2008. In 2019, during an campaign, aerial photogrammetry survey was performed, allowing for creation a detailed 3D model tower. This new dataset compared with existing Geomatics surveys (collected 2016 Terrestrial Laser Scanner) within common reference...

A triangular parabolic cross vault, that was designed by Musmeci in the 1950s as a reinforced concrete structure but remained unbuilt, is revisited from original perspective of its reinvention masonry structure. In framework static limit analysis under classical Heyman’s assumptions, generalized thrust network adopted for structural safety assessment. The performances subject to self-weight, are investigated through minimum-thrust and minimum-thickness analyses conforming geometry assuming...
The limit analysis of dry-masonry block assemblages with non-associative frictional joints is formulated as a Mixed Complementarity Problem. To overcome the computational issues due to non-convexity complementarity constraints, fixed-point based algorithm presented for constructing solution problem. Specifically, each iteration consists in straightforward associative problem, whereas fixed point sought respect normal forces at joints. comparison benchmark problems proves that resulting...
In recent years, the nonlinear response of tensegrity systems has attracted increasing attention in study mechanical metamaterials.It been shown literature that geometry and prestress an elastic structure can be designed to obtain different behaviors: stiffening, softening, snap-through behavior statics; propagation solitary waves dynamics.However, realization is challenging, because their prestressed state presence tension-only cable members.A design method for periodic lattices with null...
This paper investigates the unbuilt Musmeci parabolic vault, reinventing original reinforced concrete structure as a dry-masonry vault. In framework of rigid no-tension constitutive model with no sliding, equilibrium analysis is conducted aim ofevaluating design thickness masonry respecting shape. A parametric survey performed to assess minimum and its structural capacity under spreading supports. Attention focused on different collapse mechanisms corresponding crack patterns. For better...
