摘要

prEN 10314 provides a simple method for the determination of minimum elevated temperature yield strength values of steels on the -2s-confidence level. The method is applicable even if only a limited number of test data is available. Two data groups of steel grade X10CrMoVNb9-1 are presented in this paper to demonstrate the reliability of the method. In the present case, when the data meet the requirements concerning minimum coverage and maximum admissible residual scatter, the accuracy of the minimum values, checked by means of a simplified regression analysis, is estimated to be in the range between ±2 % of the associated minimum value of room temperature yield strength. Taking into account the uncertainty of the ratio values, deviations of that magnitude are considered acceptable.

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
