PROTEZIONE E MIGLIORAMENTO DELLE PRESTAZIONI ANTINCENDIO NEI TEATRI ALL’ITALIANA. FIRE PROTECTION AND PERFORMANCE UPGRADE IN ITALIAN STYLE THEATRES
2018
Se storicamente gli incendi sono stati la causa principale di distruzione di molti teatri all’italiana, ancora in un recente passato interventi di conservazione, restauro e adeguamento alle norme antincendio, in alcuni casi incolti e irrispettosi, ne hanno stravolto gli elementi architettonico-costruttivi caratterizzanti. Come per ogni edificio storico, ancor più nei Teatri, in cui l’effimero connota molte parti della costruzione, è necessario garantire oltre alla salvaguardia delle vite umane, la protezione dell’edificio e del suo valore intrinseco. Il processo per raggiungere livelli adeguati di prestazioni e sicurezza antincendio pone pertanto molte sfide per i legislatori, i progettisti…
Plastic load capacity and stability of frames in fire
1997
The behaviour of real construction materials in different predictable conditions is so complex that it is difficult to describe it precisely in terms of mathematical equations. The problem of the mathematical modelling of materials is, therefore, to be solved rationally by taking into consideration the material type, construction method, load value and external conditions (e.g. temperature). In ambient temperatures there is an interaction of elastic form and plastic form of steelwork failure. This interaction is described by the Merchant-Rankine formula. An analogous interaction should be expected at elevated temperatures. This paper puts forward an interaction formula for elasto-plastic cr…
Fire safety investigation for road tunnel ventilation systems – An overview
2014
Abstract In recent years, research activities about fire events in tunnel have received a significant impulse, especially after several accidents. The Computational Fluid Dynamic (CFD) has a fundamental role about. Researchers have spent resources on various topics involving numerical tools as the performance of a ventilation system, the influence of this on the air flow motion in the tunnel or the methods for fire schematization, fire-induced smoke characterization, turbulence models, etc. One of the main phenomena to consider for the safety when a fire occurs in a tunnel is the possibility of the fire-induced smoke to rise the tunnel (backlayering). A well-designed ventilation system shal…
Fire Safety in Historical Theatres (Italian-Style)
2019
The research starts from a punctual knowledge of the theatrical typology under many aspects and in-depth analysis: from the recognition of the monumental value and qualification of a historical theater, collective heritage to be preserved for future generations, we’ll investigate environmental, typological, distributive, functional, material and constructive characters in the earliest designing phases and after the adjustment and transformation interventions occurred. The main aim is identifying all the parts that are at risk of fire, the equipment implementation done to lower such a risk, with the purpose of suggesting adequate systems intended to gain a major level of fire protection in a…
Tunnel fire active protection: improving ventilation system
2019
Abstract The main aim of this work is to evaluate how the use of an active protection method, consisting in an improved forced longitudinal ventilation system, can determine a positive impact on heat extraction and people evacuation time in a tunnel fire scenario, by considering a case study which simulations are based on a real gallery.
