The mechanically based non-local elasticity: an overview of main results and future challenges
2013
The mechanically based non-local elasticity has been used, recently, in wider and wider engineering applications involving small-size devices and/or materials with marked microstructures. The key feature of the model involves the presence of non-local effects as additional body forces acting on material masses and depending on their relative displacements. An overview of the main results of the theory is reported in this paper.
Welded section defence by LRPD devices
2023
The present paper concerns a special application of some recently proposed structural devices, called LRPD, able to protect the welded sections of frame steel structures from undesired brittle collapse ensuring the good expected ductile behaviour. Standard I-shaped cross-sections are treated, and the proposed devices are suitably considered as moment resisting connections between beams and columns. At first the domain representing the brittle safe conditions is defined in the N,V,M space; then a sample plane frame subjected to seismic load conditions is studied and it is proved that, equipping the structure with the proposed devices suitably designed, the generalized stresses at the welded …
Biodeterioration of the Wooden Roof of the Phnom Penh National Museum
2017
Within the framework of a training program in Cambodia, during a visit to the National Museum in Phnom Penh, the most important in the Kingdom of Cambodia, the authors noted the presence of some signs of a termite attack in the secondary elements of the roof of an inner garden. Following this observation, a further investigation was performed in order to evaluate the phytosanitary condition of the wooden bearing element of the roof. The inspection highlighted the presence of severe decay, constituting a real danger for the integrity of the roof; consequently, an intervention of restoration, conservation and safeguard was considered to be necessary and urgent. This paper presents the results…
Photocatalytic nano-composite architectural lime mortar for degradation of urban pollutants under solar and visible (interior) light
2017
Abstract Recent advances in nano-technology and nano-additives can give enhanced properties to natural hydraulic lime (NHL), creating a multifunctional material. We have prepared a novel nanocomposite, made of a commercial mortar with 1 wt% and 5 wt% added titania nanoparticles (NPs). These TiO 2 NPs are themselves doped with 1 mol% silver, to give the material enhanced photocatalytic and antimicrobial properties. The Ag-doped TiO 2 NPs were made from a simple, costs effective, aqueous green nanosynthesis process, and the end material only contains 0.01–0.05% Ag. As this mortar is intended to both combat atmospheric pollution, and create more durable/lower maintenance building facades (plas…
