Abstract: In structural design of steel structures in fire, the failure criterion needs to be checked for all members under individual design actions or a combination of them. For space frames, combined design actions usually include ...

Abstract: This paper presents the use of plastic analysis methods for the calculation of critical temperature distribution for structures at collapse under fire conditions. The methods are based on the well-known plastic hinge concept ...

Abstract: In current design practice for steel structures in fire, the temperature profile of a steel member will not change with its locations if it is subject to the same fire environment according to a certain standard or natural ...

Abstract: A numerical method, with which experimental results were processed, was adopted to measure the total emissivity of mild steel specimens at high temperatures. This method is derived from considering the transient thermal ...

Abstract: A heat transfer model for unprotected steel structural members was proposed in this study. The model accounts for both the variation of the steel emissivity during the fire growth and the view factor effect. The participation ...
