Innovative Structural Engineering for Tall Buildings in Fire

摘要: In response to public demand for safer structures and the commercial drive robust structural fire design post 9-11, authors have carried out a number of analyses behaviour long span floor systems including composite cellular beams truss floors similar World Trade Centre (WTC) 1 2 buildings. The research has considered single multi-storey fires. For scenarios where fires been assumed act over several storeys simultaneously this is beginning identify potential global progressive collapse mechanisms in different long-span studied. Wherever possible, failure are being validated against evidence from real such as those WTC, Torre Windsor, others. studies so far provided substantial increase understanding whole frame high-rise buildings fire, but work continues progress new designs analyzed. intent that will form basis appropriate, always based on risk assessment, induced by aim propose do not rely solely traditional protection measures, specific detailing can demonstrate their capability withstand these events. other words, they intrinsically rather than totally reliant added safety measures fail extreme This paper present some results recent show how it implemented through case study office building proposed UK.
