  • Behavior of Structures in Fire and Real Design - A Case Study 

    Lamont, Susan; Lane, Barbara; Flint, Graeme; Usmani, Asif (Society for Fire Protection Engineers, 2006)
    A great deal of understanding into the behaviour of composite steel-concrete structures in fire has been developed since the Cardington frame fire tests (UK) 1990s. This has now been broadened so that structures in fire ...
  • The behaviour of concrete structures in fire 

    Fletcher, Ian A; Welch, Stephen; Torero, Jose L; Carvel, Ricky O; Usmani, Asif (2007-03-29)
    The nature of concrete-based structures means that they generally perform very well in fire. However, concrete is a complex material and its properties can change dramatically when exposed to high temperatures. This paper ...
  • Bonded Fibre Reinforced Polymer Strengthening in a Real Fire 

    Stratford, Tim J; Gillie, Martin; Chen, J; Usmani, Asif (Advances in Structural Engineering by Multi Science Publishing, 2010-01)
    FRP strengthening is critically dependent upon the bonding adhesive. The adhesive used is typically an ambient cure epoxy with a glass transition temperature as low as 60ºC. This paper describes the performance of bonded ...

    Usmani, Asif; Flint, Graeme; Jowsey, Allan; Roben, Charlotte; Torero, Jose L (2006-10)
    This paper presents a summary of the author’s investigation into the collapse of tall buildings. A large number of computational analyses have been carried out at the University of Edinburgh (UoE) over the last 4 years ...
  • Determination of Fire Induced Collapse Mechanisms of Multi-Storey Steel Framed Structures 

    Jowsey, Allan; Torero, Jose L; Usmani, Asif; Lane, Barbara; Lamont, Susan (4th European Conference on Steel and Composite Structures, 2005-06)
    Following the events of September 11th 2001, understanding the performance of multi-storey buildings during large-scale fires has assumed greater importance. These events have highlighted the possibility of large uncontrolled ...
  • FireGrid: An e-infrastructure for next-generation emergency response support 

    Han, Liangxiu; Potter, Stephen; Beckett, George; Pringle, Gavin; Welch, Stephen; Koo, Sung-Han; Wickler, Gerhard; Usmani, Asif; Torero, Jose L; Tate, Austin (Elsevier Journal of Parallel and Distributed Computing, 2010)
    The FireGrid project aims to harness the potential of advanced forms of computation to support the response to large-scale emergencies (with an initial focus on the response to fires in the built environment). Computational ...
  • FireGrid: Integrated emergency response and fire safety engineering for the future built environment 

    Berry, Dave; Usmani, Asif; Torero, Jose L; Tate, Austin; McLaughlin, Stephen; Potter, Stephen; Trew, Arthur; Baxter, Rob; Bull, Mark; Atkinson, Malcolm (UK e-Science Programme All Hands Meeting, 2005-09-20)
    Analyses of disasters such as the Piper Alpha explosion (Sylvester-Evans and Drysdale, 1998), the World Trade Centre collapse (Torero et al, 2002 , Usmani et al, 2003) and the fires at Kings Cross (Drysdale et al, 1992) ...
  • FireGrid: Integrated emergency response and fire safety engineering for the future built environment 

    Berry, Dave; Usmani, Asif; Torero, Jose L; Tate, Austin; McLaughlin, Stephen; Potter, Stephen; Trew, Arthur; Baxter, Rob; Bull, Mark; Atkinson, Malcolm (National eScience Centre, Edinburgh, 2005-05)
    FireGrid is researching the development and integration of modelling, sensors, Grid, HPC, and C/C technologies. It will stimulate further research, in new safety systems and strategies, in new sensor technologies, in ...
  • How did the WTC towers collapse: a new theory 

    Usmani, Asif; Chung, Y. C.; Torero, Jose L (Fire Safety Journal, 2003-10)
    This paper uses a finite element model to investigate the stability of the Twin-Towers of the World Trade Center, New York for a number of different fire scenarios. This investigation does not take into account the ...
  • Introduction to FireGrid 

    Welch, Stephen; Usmani, Asif; Upadhyay, Rochan; Berry, Dave; Potter, Stephen; Torero, Jose L (The University of Edinburgh, 2007-11-14)
    FireGrid is an ambitious and innovative project, seeking to develop the technology to support a new way of managing emergency response in the modern built environment. Specific novel aspects include the integration of ...
  • Light Steel Framing: Improving the Integral Design 

    Amundarain, Aitor; Torero, Jose L; Usmani, Asif; Al-Remal, Ahmad M (Global Built Environment: Towards an Integrated Approach for Sustainability, Lancashire (UK), 2006-09-11)
    Light Steel Framing has been extensively used in cold climate countries due to its good thermal and structural behaviour. Improved thermal behaviour results in positive environmental impact essential for sustainable ...
  • Modelling heated composite floor slabs with reference to the Cardington experiments 

    Gillie, Martin; Usmani, Asif; Rotter, J Michael (Elsevier, 2001)
