Valencia, November 15 (EFE) .- A Researchers from the Polytechnic University of Valencia has developed a new methodology that enables the automatic design of highway bridges less cost and carbon dioxide emissions based on observing the behavior of fireflies.
According It is reported the UPV in a statement, this work is published in the journal “Automation in Construction” and is the work of researchers Victor Yepes, Jose Marti and Tatiana Garcia.
One of the main conclusions is the social behavior of fireflies can help design more efficient bridges, especially those that are installed on roads that are supported by prestressed concrete beams prefabricated cross section double U.
From the labs Institute of Science and Technology of Concrete (Icitech) of the UPV, these researchers have developed a method to minimize emissions of carbon dioxide in the process of construction and also the costs.
Explains Victor Yepes, fireflies collectively behave intelligently and social behavior based on light emitting (luciferin).
“Their most distinctive feature is the night procession, when males roam in search of couples with a characteristic flight while emitting sequences of flashing light own species, “he says.
” The females of the same species may respond with specific highlights and so mating can occur. Each firefly selected using a probabilistic mechanism, a neighbor who has his own highest value of luciferin and moves toward him, “he adds.
” Translating this behavior to the design of bridges, is have achieved savings of between 20 and 50% over the actual bridge design, “said the professor.
In the development of the new methodology, researchers have used an algorithm in which the structure Bridge is defined from 40 variables, including the types of materials and armor of the beam and slab.
The algorithm considers each bridge as a firefly, so a bridge retail cost or emissions presents a higher value of luciferin, ie, it is more promising in the search for better solutions, a principle that allows to optimize its design, says Victor Yepes.
In addition, the results indicate that On average, the reduction of one euro cost saving up to 1.75 kilos of carbon emissions, responsible for global warming dioxide.
To test the effectiveness of this new methodology, researchers the Icitech applied it to the design simulation of a real bridge, namely the viaduct 1 stretch Muro de Alcoy-Port Albaida construction project of the Mediterranean motorway.
“Applying our methodology The total cost of the bridge would have been optimized to 50% cheaper, without sacrificing quality or safety, “says Victor Yepes.
This work is part of Horsost project, funded by the Ministry of Economy and Competitiveness.
