Fast Data Assimilation in Fire Tests of Steel Members

Please always quote using this URN: urn:nbn:de:0297-zib-3766
  • This report presents a fast data assimilation method to produce an interpolating time and space temperature distribution for steel members subject to fire testing. The method assimilates collected temperature data into the numerical integration of the heat equation. This physically based method also allows the computation of lateral and axial heat flux into and inside the member.
