摘要

This paper describes effect of hot dip galvanizing of steel structure surfaces to temperature of steel members in the fire conditions. Temperature of the set of specimens was measured during the second fire test at experimental building in Veseli nad Luznici. Experiment results show, that the zinc coating can reduce temperature in steel members especially in the first fifteen minutes of the fire. The paper describes specimens, which were used for fire test, shows testing procedure and compares measured temperatures of specimens with and without zinc coated surface. The paper also describes the process of analytical evaluation and based on the results of this evaluation specifies value of the surface emissivity for zinc coated steel members in the fire conditions.

7. Mechanical properties of various concrete after high temperature exposure Mechanical property of various types of concrete after high temperature exposure is investigated. Considering compressive strength requirement for a vertical element in high rise building, concrete specimens with various design strengths of 35, 80, 100, and 150 MPa were tested. Particularly, the influence of incorporated steel fiber on fire resistance is of interest in this study. Experimental results show that the fire resistance depends on the design strength and steel fiber content. Normal strength concrete (NSC) of a design strength of 35 MPa or high performance concrete (HPC) of 80-100 MPa does not spall when exposed to 100-400 °C of temperature. However, an explosive spalling occurs at 300 °C when the HPCs contain 1 vol. of steel fiber. Ultra-high performance concrete (UHPC) of a design strength of 150 MPa and 1.5 vol. of steel fiber also shows dramatic spalling at 300 °C. The experimental results found in this study can contribute to a better understanding of the behaviors of HPC and UHPC under fire and the role of steel fiber on the fire resistance. [O] . 2017
