The Suspension Iron Bridge of the Early 19 th Century Villa Borghese in Florence (Italy) CECCHI Alberto1,a, PASSERINI Alessio 2 and SALVESTRINI Daniele2 1 Department of Civil Engineering, University of Florence, Florence, Italy; 2 Leonardo Società di Ingegneria S.r.l., Florence, Italy a alberto.cecchi@unifi.it Abstract: Between the 1825 and the 1828, Antonio Carcopino, an engineer, designed a suspension iron cable bridge: this fact shows the interest of the Borghese family for the technological innovations of the 18 th and of 19th century.
After the Emperor's death, in 1825 the Prince bought a Villa in Quinto in the suburbs of Florence, which he restored in Neoclassical style: Antonio Carcopino, an engineer, scholar of the Academy of Fine Arts of Florence, designed the villa and the garden (Fig. 1) between the 1825 and 1828.
According to our knowledge, this bridge is the oldest iron cable suspension bridge surviving of the period, together with the much longer one (1826-1832) on the river Garigliano (unfortunately destroyed and recently rebuilt) whose designer is the engineer Luigi Giura of the "Corpo borbonico di ponti e strade".
The work of Gilbert shows as the mathematician has contributed to the engineering plans and designs of that time.
The Funicular Polygon We do not know if Carcopino knew Navier's memory: but surely the Florentine engineer Alessandro Manetti, as Navier in 1806, had been a student of the École nationale des ponts et chausses since 1809, and Navier could have influenced Manetti.

Design and Research of Electronics Factory Evacuation Based on Computer Simulation Technology Bai Lei1,a 1School of Architecture, Xi’an University of Architecture and Technology, Xi’an 710055, China abob-kid@163.com Keywords: Electronic factory, simulation technology Abstract: Along with the development of economy, a growing of large electronics workshop projects and the increasing of workshop area, the difficulties of evacuation design in engineering design is increasingly protruding.
By using the method of performance-based fire protection design in electronic workshop personnel evacuation design, and using computer simulation technology to demonstrate its security, we can find the solution to similar engineering problems. 1.
Safety evacuation exits of the support area on the first layer open to outdoor directly, and evacuate personnel directly to the outside. 4.Demonstration of the program The program demonstration is based on the engineering theory of architectural fire safety, using the fire and evacuation simulation software to analyze whether the program can meet the requirements of safe evacuation in case of fire.
Fire power Considering the fire scenario needs protection from the sprinkler system, the fire power should refer to Shanghai’s “Technical Specification for Civil Smoke (DGJ08-88-2006)”.
