Abstract

Cross-laminated timber (CLT) panels are relatively new engineered wood products that can be used as load bearing walls, floors and roof elements in innovative and high quality modern timber structures. The fire behavior of cross-laminated timber panels requires careful evaluation to allow the expansion of CLT elements usage in buildings. A University of British Columbia study has been conducted at the Trees and Timber Institute CNR-IVALSA in San Michele all’Adige, Italy to experimentally evaluate the fire performance of Canadian CLT panels. In total, ten loaded fire tests were performed using standard fire curves (ULC/ASTM and ISO) to study the influence of different cross-section layups on the fire resistance of floor and wall elements and to investigate the influence of different anchors on the fire behavior of wall elements. This paper presents the main results of the experimental analyses and discusses in particular the charring rate, one of the main parameters in fire design.
荷载交叉层压木墙和地板构件的防火试验
交叉层压木材(CLT)板是相对较新的工程木制品,可以用作创新和高质量的现代木结构的承重墙,地板和屋顶元素。交叉层压木板的防火性能需要仔细评估,以允许在建筑物中扩展CLT元素的使用。英属哥伦比亚大学的一项研究在意大利圣米歇尔的树木和木材研究所CNR-IVALSA进行,实验评估了加拿大CLT面板的防火性能。采用标准火灾曲线(ULC/ASTM和ISO)进行了10次加载火灾试验,研究了不同截面布置对楼板和墙体构件耐火性能的影响,并探讨了不同锚杆对墙体构件耐火性能的影响。本文介绍了实验分析的主要结果,并着重讨论了燃烧设计的主要参数之一——炭化率。
