...Andrei Kervalishvili; Ivar Talvik Purpose This paper aims to reliability analysis of axially loaded steel columns at elevated temperatures considering the probabilistic features of fire. Design/methodology/approach The response function used in the reliability analysis is based on the non...

... during a fire test, and propose a compensation scheme to mitigate instabilities in the hybrid testing procedure. Design/methodology/approach The paper focuses on structural steel columns and starts with a detailed literature review of steel column fire tests in the past few decades with varying axial...

...Tiago A. de C. Pires; João Paulo C. Rodrigues; Jose J.R. Silva Purpose Nowadays, circular concrete-filled tubular (CFT) columns are largely used in construction because of structural and architectural advantages such as high load bearing capacity and aesthetic appearance. The behavior of CFT...

... the axial capacity of RC columns exposed to standard fire. Design/methodology/approach The average temperature distribution along the section height is first predicted for a specific fire scenario. The corresponding distribution of the reduced concrete strength is then integrated to develop expressions...

... to thermal elongation, the failure is controlled by the temperature increasing. Originality/value This paper is a contribution to the knowledge on the behavior of cold-formed steel columns subjected to fire, especially on the ones with a built-up cross-section, where results on thermal restrained ones...

... and columns exposed to various heating regimes. The paper further evaluates the implicit consideration of creep in the Eurocode 3 steel material model. Originality/value A modified Eurocode 3 carbon steel material model for creep-free analysis is proposed for general structural fire engineering analysis...

...Jean-Marc Franssen; Bin Zhao; Thomas Gernay Purpose The purpose of this paper is to gain from experimental tests an insight into the failure mode of slender steel columns subjected to fire. The tests will also be used to validate a numerical model. Design/methodology/approach A series...

...Ruirui Sun; Ian Burgess; Zhaohui Huang A static/dynamic version of the software Vulcan has recently been developed, in which the numerical singularity of a static analysis, induced by a local instability of a structure, for instance the buckling of a column, can be covered by switching...
