Texte intégralWhen an explosive detonates above ground, air is principally the only material involved in the transmission of shock waves that can result in damage. Hydrodynamic codes that simulate these explosions use equations of state (EOSs) for modeling the behavior of air at these high-pressure, high-velocity conditions. An investigation is made into the effect that the EOS selection for air has on the calculated overpressure-time waveforms of a blast event. Specifically, the ideal gas, Doan-Nickel, and SESAME EOSs in the SHAMRC code were used to reproduce experiments conducted at the Blast Load Simulator (BLS), a large-scale shock tube operated by the U.S. Army Engineer Research and Development Center, that consisted of subjecting an instrumented rigid box at three angles of orientation inside the BLS to a blast environment. Numerical comparisons were made against experimentally-derived confidence intervals using peak values and several error metrics, and an attempt was made to rank the EOS based on performance. Issues were noted with the duration of decay from maximum pressure to negative phase that resulted in a general underprediction of the integrated impulse regardless of EOS, while the largest errors were noted for gages on faces at 45 to 90 degrees from the initial flow direction. Although no significant differences were noticed in the pressure histories from different EOSs, the ideal gas consistently ranked last in terms of the error metrics considered and simultaneously required the least computing resources. Similarly, the Doan-Nickel EOS slightly performed better than SESAME while requiring additional wallclock time. The study showed that the Doan-Nickel and SESAME EOSs can produce blast signatures with less errors and more matches in peak pressure and impulse than the ideal gas EOS at the expense of more computational requirements.

Texte intégralRecentemente, la richiesta architettonica sempre più spinta di trasparenza e luminosità ha favorito la diffusione nell’edilizia del vetro come materiale da costruzione. Sebbene si tratti di un materiale ancora poco conosciuto rispetto ad altri materiali convenzionali, il vetro trova, infatti, ampia applicazione nelle realizzazioni strutturali più innovative. Anche se le soluzioni architettoniche proposte trovano ampio consenso, spesso la difficoltà principale consiste nel dimensionare adeguatamente tali elementi e nel preservarne l’integrità da eventuali fenomeni di instabilità. Con riferimento a questo tema, nella presente tesi vengono proposte alcune significative formulazioni analitiche per la verifica di stabilità di elementi in vetro monolitico, stratificato o vetro-camera, con particolare attenzione per il comportamento di travi compresse, travi inflesse, pannelli sottoposti a compressione nel piano o taglio nel piano. Allo stesso tempo, viene studiato il comportamento di facciate in vetro-acciaio sottoposte a carico da esplosione, con riferimento specifico a due tipologie di facciata note come facciate continue a lastre indipendenti, controventate da un sistema di cavi pretesi, e facciate a pannelli, nelle quali le lastre di vetro sono sostenute da un telaio metallico di supporto. Per ciascuna tipologia di facciata, vengono evidenziate le criticità dovute a carichi da esplosione di varia intensità mediante opportuni modelli numerici. Inoltre, viene analizzato l’effetto di eventuali dispositivi in grado di mitigarne le componenti principali assorbendo e/o dissipando parte dell’energia d’ingresso associata all’evento esplosivo.
Recently, due to aesthetic and architectural requirements of transparency and lightness, the use of glass as a structural material showed a strong increase. Although its load carrying behavior is actually not well-known, glass finds large application in modern and innovative buildings. Nevertheless, the main difficulties are related to the proper design of these structural elements and in the preservation of their integrity, avoiding possible buckling phenomena. In this context, this Doctoral Thesis proposes a series of interesting analytical formulations suitable for the buckling verification of monolithic, laminated, insulated structural glass element, with particular attention for the load carrying behavior of beams in compression or in bending, as well as for the buckling response of glass panels subjected to in-plane compression or shear. At the same time, the Thesis focuses also on the dynamic behavior of two different typologies of steel-glass façades subjected to air blast loads, whit particular attention to the analysis of cable-supported façades and conventional curtain walls, in which a metallic frame supports the glass panels. In both the circumstances, accurate numerical simulations are performed to highlight the criticalities of similar structural systems, in presence of high-level or medium / low-level air blast loads. Finally, the structural benefits of possible devices able to mitigate the effects of explosions in the main components of these façades, by partly storing / dissipating the incoming energy, are investigated numerically and analytically.
