摘要

文章研究了中欧最常见的硬木树种山毛榉的炭化和炭化前温度。现行的欧洲规范标准 EN 1995-1-2 规定炭化前温度为 300 \(^{\circ }\)C ,尽管这一规定主要适用于软木树种。因此,本文旨在研究这一假设是否适用于榉木。通过先进的实验分析和数值建模,确定了榉木的炭化前温度超过 300 \(^{\circ }\)C 。这一发现是正确验证榉木结构件耐火设计的关键信息。此外,它还为改进简化的防火设计方法,特别是更准确地确定炭化深度奠定了基础。

On the char front temperature of beech (Fagus sylvatica)

The article investigates the charring and the char front temperature of beech, the most widespread hardwood species in Central Europe. The current Eurocode standard EN 1995-1-2 specifies the char front temperature to be 300 \(^{\circ }\)C, albeit this determination primarily applies to softwood species. Consequently, this article aims to examine whether this assumption applies to beech. Through advanced experimental analysis and numerical modelling, it was determined that the char front temperature for beech exceeds 300 \(^{\circ }\)C. This finding represents crucial information for the correct validation of fire-resistant design for structural elements made of beech. Moreover, it lays the groundwork for improving simplified methods of fire design, particularly for a more accurate determination of the charring depth.

期刊介绍: Wood Science and Technology publishes original scientific research results and review papers covering the entire field of wood material science, wood components and wood based products. Subjects are wood biology and wood quality, wood physics and physical technologies, wood chemistry and chemical technologies. Latest advances in areas such as cell wall and wood formation; structural and chemical composition of wood and wood composites and their property relations; physical, mechanical and chemical characterization and relevant methodological developments, and microbiological degradation of wood and wood based products are reported. Topics related to wood technology include machining, gluing, and finishing, composite technology, wood modification, wood mechanics, creep and rheology, and the conversion of wood into pulp and biorefinery products.
