Abstract: This paper reports test results showing how the heating-cooling process like the one occurring during fire action can affect the tensile strength and the strain after rupture of the steels normally used in reinforced and ...

Abstract: Composite columns consisting of steel hollow sections filled with concrete offer numerous advantages including high fire resistance. However, there are limited provisions for fire design of these columns, and current ...

Abstract: Experimental results are reported on the compressive strength of steel fiber high-strength concrete (SFHSC) subjected to high temperatures. The concrete specimens were preheated to different temperature levels, and the ...
