10 points to consider in fires of steel-framed buildings (1/11)

The Cardington Fire Tests were a series of large-scale fire tests conducted in real steel-framed structures at the village of Cardington, Bedfordshire, England.

Funded by the Secretary of State for the Environment, Transport and the Regions Partners in Technology, the BRE Centre for Fire Safety Engineering (previously the Structures in Fire Group) at the University of Edinburgh conducted the experimental series in 2000. After the test, the group conducted extensive computational and analytical studies of the behaviour of steel-framed composite structures in fire conditions. This work was undertaken in collaboration with the Corus Group and Imperial College London.

In the following video you can see a sequence of the test in 2003.

the next slides show a resume of this work and which are the hot points of this research.

 

This research is very important for firefighters as they can know approximately how long they will be able to stay into the structure before it collapses. But… Which are the most important points you should consider to make ready this attack? Leave your comment.

10 puntos a tener en cuenta en fuegos de edificaciones con estructuras de acero. (1/11)

 

The Cardington Fire Tests fueron una serie de test a gran escala realizados en estructuras reales de acero en el pueblo de Cardington, Bedfordshire, England.

Fundado por el secretario de estado para el medio ambiente, transporte y las regiones asociadas en tecnología, El  BRE, centro de ingeniería para la seguridad del fuego (anteriormente grupo de fuego en estructuras) en la universidad de Edinburgo, llevo a cabo esta serie experimental en el año 200. Despues del test, el grupo llevó a cabo extensos estudios computacionales y analíticos del comportamiento de estructuras de materiales compuestos de armazón de acero en caso de incendio. Este trabajo fue realizado en colaboración con el Grupo Corus y el Imperial College de Londres.

En el siguiente video se puede ver una secuencia de la prueba en 2003.

La siguiente presentación muestra un resumen del trabajo realizado y cuáles son los puntos a tener en cuenta en esta investigación. A pesar de que la presentación está realizada en inglés, no contiene mucho texto y este no supone un obstáculo para la comprensión del tema.

 

Esta investigación es muy importante para los servicios de bomberos, ya que podrían calcular aproximadamente el tiempo que pueden permanecer en su interior antes de que esta colapse, en caso de que fuera necesario. Pero ,¿cuáles son los puntos principales que se deben analizar antes de abordar este tipo de intervención?. Deja tu comentario.

Atlas, iron firefighter.

Sometimes firefighters have to risk their lives in many situations that there is no survive possibilty. For this reason, Pentagon has started a competition to develop a robot which will be able to work in extremely hazardous situations.

He is a hydraulically powered robot and they call him Atlas. The Pentagon-financed humanoid robot was unveiled to the public today.

His mission is as noble as it gets: help rescue missions in cases of natural and man-made disasters, especially in situations where humans cannot survive – the ultimate firefighter, that is.

And some of its features include laser and stereo vision systems, as well as dexterous hands.

The Pentagon has put on a challenge in which competing teams of technologists program it to do things like shut off valves or throw switches, open doors, operate power equipment and travel over rocky ground. The winner will be rewarded with a $2 million check.

¿It´s that the beginning of the end of firefighters?, I would like to known your opinion, leave your comment.
