Mechanical properties of structural steel at elevated temperatures and after cooling down
Jyri Outinen,Pentti Mäkeläinen +1 more
TL;DR: In this article, the experimental test results for the mechanical properties of the studied steel grades S350GD+Z, S355 and S460M at fire temperatures are presented with a short description of the testing facilities.
Journal ArticleDOI
Fire design model for structural steel S355 based upon transient state tensile test results
TL;DR: In this paper, the authors used the transient state tensile test (TST) method to model the stress-strain relationship of the structural steel S355 at temperatures 20-700°C.
Journal ArticleDOI
Prediction of mechanical properties of light gauge steels at elevated temperatures
TL;DR: In this paper, an experimental study into the deterioration of mechanical properties for both low and high strength light gauge steels under elevated temperatures was conducted to derive accurate reduction factors for mechanical properties in fire safety design.
Journal ArticleDOI
Parametric temperature–time curves of medium compartment fires for structural design
Zhongcheng Ma,Pentti Mäkeläinen +1 more
TL;DR: In this article, a parametric temperature-time curve for structural fire design purposes is developed for small and medium compartment fires, which can be used to estimate the temperature history of a fully developed compartment fire.
Journal ArticleDOI
The longitudinal shear behaviour of a new steel sheeting profile for composite floor slabs
Pentti Mäkeläinen,Ye Sun +1 more
TL;DR: In this paper, the shear-connection behavior of composite slabs with a particular profiled steel sheeting having a depth of 153 mm is experimentally studied, and it is found that the reduction of Young's modulus caused by the penetrated embossments is an important factor that affects the determination of the depth and width of the embozments.
