Predicting the fire resistance behaviour of high strength concrete columns
TL;DR: In this paper, a numerical model, in the form of a computer program, for tracing the behavior of high performance concrete (HPC) columns exposed to fire is presented. But the model is limited to the case of HPC columns and cannot be used to predict the fire resistance of any value of the significant parameters, such as load, section dimensions, fiber reinforcement, column length, concrete strength, aggregate type, and fiber reinforcement.

Experimental study on post-fire mechanical properties of high strength Q460 steel
TL;DR: In this article, the residual strength of high strength Q460 steel structures after fire was evaluated and two cooling methods were considered, namely, natural air cooling and cooling by water, and it was found that post-fire mechanical properties were significantly reduced below the original ambient temperature mechanical properties if they had been exposed to temperatures exceeding 600°C.
