Simplified Formulation of Solution for Beams on Winkler Foundation allowing Discontinuities due to Loads and Constraints
2009
The paper discusses material for a course in Structural Mechanics addressed to second-Year Civil Engineering students. The response of beams on a Winkler foundation characterized by discontinuities in both the displacements (deflections and/or slopes) and forces (internal forces and/or loads) is studied. In particular, a simplified formulation for the solution of the discontinuous differential equation governing this problem is given. In some cases, the formulation is able to give the exact solution in a closed form. This is made possible through the use of the generalized functions, such as the well-known Unit Step Function and the Dirac delta function. The cases of discontinuities due to …
Bio-based Materials. Standardizzazione e processi per la commercializzazione
2021
Il contributo si occupa degli aspetti normativi nel campo della produzione e uso di una malta con componenti organici derivanti dal riciclo di scarti agricoli e silvo-pastorali. Viene prestata attenzione alla normativa internazionale più diffusa e nota, a quella europea e a quella italiana. La riduzione del consumo di suolo e di risorse lapidee, degli scarti, la limitazione dell’utilizzo di materiali di cava naturali sono solo alcuni benefici che hanno indotto la comunità scientifica a investire nell’uso di materie prime-seconde di origine vegetale, ecosostenibili; oggi, lo stato dell’arte è molto ricco. Tuttavia, non ci sono ancora normative tecniche e procedurali relative ai materiali che…

Testo di presentazione e progetto architettonico realizzato nell’ambito di una ricerca interdipartimentale sul centro storico di Caltabellotta. L’intervento riguarda la sistemazione di un’area scenografica della città in cui i temi della natura e dell’archeologia vengono interpretati e restituiti da una soluzione architettonica.
Soluzioni basate sulla natura per le città portuali. L’approccio “Building with nature” e i limiti di trasferibilità nel contesto italiano
2022
Achieving sustainable development goals in port cities is an increasingly challenging task as the trend is toward their expansion for global competition, thus increasing their impacts on soil, atmosphere, water, and marine and terrestrial ecosystems. The present contribution proposes to explore the Building with Nature approach developed by EcoShape and Deltares in the Dutch context through the comparison of case studies and to highlight some critical issues in its transferability to the Italian context.
Analytical solution for the transient response of symmetric magnetoelectric laminated beams
2010
In this paper an analytical solution is presented for the forced vibration problem of magnetoelectric symmetric laminated beams. In deriving the mathematical model the Timoshenko’s beam theory is used and the electric and magnetic fields are assumed to be quasi-static. The model is written for a magnetoelectric sensing device by applying proper magnetoelectric boundary conditions on the beam top and bottom surfaces. The model highlights that the magneto-electro-mechanical couplings affect the bending stiffness and that the magnetoelectric inputs can be treated as equivalent bending moments. Forced vibration analyses are presented to assess the reliability of the solution.

Theoretical Predictions and experimental determination of cloud point curves for polymeric solutions: an application to the ternary system Poly-lacti…
2011
The lattice fluid model with specific interactions was applied to the ternary system Poly-L-lactic-acid (PLLA)-dioxane-water. Model parameters were determined by fitting experimental data. The as-obtained parameters were used to calculate the complete phase diagram. An experimental apparatus for cloud point measurements, which is under construction, is presented.
