Huang, S-S. and Burgess, I.W. (2012) Effect of transient strain on strength of concrete and CFT columns in fire – Part 2: Simplified and numerical modelling. Engineering Structures, 44. 389 - 399. ISSN 0141-0296
Abstract
This paper presents finite element analysis on columns of concrete and concrete-filled tubular section. This study has been conducted with Vulcan, a specialist structural fire engineering FE program, which has been further developed to incorporate the transient strain of concrete. The implementation of transient strain in Vulcan has been validated against a Shanley-like simplified model. A further extension of the simplified model has been carried out in order to provide direct comparability with the FE modelling. The effects of transient strain, considering thermal gradients through the column cross-section, have been evaluated with both the simplified and FE models. Finally, parametric studies on concrete-filled tubular columns, considering the effects of slenderness ratio, reinforcement, the steel casing and thermal gradient within the cross-section, have been conducted using Vulcan.
