Buckling analysis and design proposal for 2-side supported double Insulated Glass Units (IGUs) in compression

Chiara Bedon, Claudio Amadio

Engineering Structures > 2018 > 168 > C > 23-34

Due to mainly thermal and energy potentials, Insulated Glass Units (IGUs) are largely used in modern buildings to realize curtain walls and enclosures. The typical IGU consists of two glass layers, either monolithic and/or laminated, joined together by enclosing an hermetically-sealed air (or gas) cavity between them. There, maximum stresses and deformations derive from external pressures (wind loads,...

Chiara Bedon, Manuel Santarsiero

Advanced Engineering Materials > 20 > 5 > n/a - n/a

The consistent architectural transparency demand in buildings is highly promoting the structural use of glass, in combination or to replace load‐bearing components made of traditional constructional materials. Despite its huge application in facades, roofs, envelopes, frame components, however, glass still represents a rather innovative and not well‐known material, requiring specific design conceptsm...

Glass facades under seismic events and explosions: a novel distributed-TMD design concept for building protection

Chiara Bedon, Claudio Amadio

Glass Structures & Engineering > 2018 > 3 > 2 > 257-274

Glazing facades generally represent one of the most critical building components, from a structural point of view, since providing a physical separation and barrier for the building occupants. In this regard, especially under the action of extreme loads, they require specific design concepts voted to protect the building occupants. In this paper, the feasibility and potential of special mechanical...

Performance of structural glass facades under extreme loads – Design methods, existing research, current issues and trends

Chiara Bedon, Xihong Zhang, Filipe Santos, Dániel Honfi, more

Construction and Building Materials > 2018 > 163 > C > 921-937

Glass has been overwhelmingly used for windows and facades in modern constructions, for many practical reasons, including thermal, energy, light and aesthetics. Nevertheless, due to the relatively low tensile strength and mostly brittle behaviour of glass, compared to other traditional materials, as well as to a multitude of interacting structural and non-structural components, windows/facades are...

Enhancement of the seismic performance of multi-storey buildings by means of dissipative glazing curtain walls

Chiara Bedon, Claudio Amadio

Engineering Structures > 2017 > 152 > C > 320-334

Glazing facades are widely used in building structures, due to a series of aesthetic, thermal, lightening aspects. From a structural point of view, under the action of exceptional loads as impacts, explosions or seismic events, the glazing envelopes often represent the critical component for multi-storey buildings, due to the typically brittle behavior and limited tensile resistance of the glass panes,...

Numerical assessment of slab-interaction effects on the behaviour of steel-concrete composite joints

Claudio Amadio, Chiara Bedon, Marco Fasan

Journal of Constructional Steel Research > 2017 > 139 > C > 397-410

In current design practice for seismic resistant steel braced frames, general rules and standard provisions are aimed to ensure a structural behaviour for beam-to-column joints of non-braced spans as close as possible to perfect hinges. This is done to prevent any kind of interaction with the bracing systems, in particular under horizontal loads. However, the global performance of composite joints...

Assessing the structural behaviour of square hollow glass columns subjected to combined compressive and impact loads via full-scale experiments

Roman Kalamar, Chiara Bedon, Martina Eliášová

Engineering Structures > 2017 > 143 > C > 127-140

Glass is largely used in buildings as a novel construction material. Due to the intrinsic mechanical properties of such material, however, specific design recommendations are demanded in order to offer appropriate “fail-safe” requirements. This is especially true in the case of load-bearing structural glass elements where redundancy, stability and residual resistance should be guaranteed. In this...

Derivation of buckling design curves via FE modelling for in-plane compressed timber log-walls in accordance with the Eurocode 5

Chiara Bedon, Massimo Fragiacomo

European Journal of Wood and Wood Products > 2017 > 75 > 3 > 449-465

In ‘Blockhaus’ systems the structural capacity derives from surface interactions and friction mechanisms between multiple timber logs stacked horizontally one upon each other. Unlike masonry or concrete walls, timber log-walls are characterized by the absence of a full structural interaction between the basic components, hence resulting in ‘assembled’ rather than ‘fully monolithic’ structural systems...
