Statistical Properties of Compressive Strength of Thick Fireproof Coating for Steel Structure

本文针对厚型钢结构防火涂层的抗压强度展开了批量试验研究,分析了厚型防火涂层的受压破坏特征,并通过对所得试验结果的数理统计分析,获得了防火涂层抗压强度、弹性模量和极限应变的统计特性和取值。本文研究有助于进一步认识厚型钢结构防火涂层的力学性能,并为准确评价钢结构的震后抗火性能提供材性分析数据。

In this paper, batch tests have been conducted to obtain compressive strength of fireproof coating. The damage characteristic of the coating is analyzed, and the strength value, modulus of elasticity and ultimate strain under compressive loading are obtained through the statistical analysis. The finding from this paper helps to understand the mechanics properties of cementitious fireproof coating, and provides the coating material property data for the analysis of the residual fire resistance of a steel frame.
