Abstract

This paper looks at the mechanical behaviour of wood-based beams. Laboratory tests of an I-beam show a considerable decrease of capacity in the weakened zones, e.g., at the connection between two pieces of pine wood used as a flange. We propose strengthening of the zones using fibre composite tapes based on CFRP. This article demonstrates the way for protection of the I-beam with defects in the bottom flange against the loss of load-carrying capacity. The required anchor length is determined by an analytical method formulated in the paper. The numerical results are presented. The full adhesion between CRFP and wood is assumed in the numerical simulations.

木基复合材料梁的薄弱区及其CFRP加固：实验、理论和数值分析

本文研究了木质梁的力学性能。工字钢的实验室测试表明，弱化区的承载力显著降低，例如，用作法兰的两块松木之间的连接处。我们建议使用基于CFRP的纤维复合带加固这些区域。本文介绍了底翼缘有缺陷的工字钢的承载力损失防护方法。所需的锚固长度是通过本文中制定的分析方法确定的。给出了数值结果。在数值模拟中假设CRFP和木材之间完全粘附。

期刊介绍： Engineering Transactions (formerly Rozprawy Inżynierskie) is a refereed international journal founded in 1952. The journal promotes research and practice in engineering science and provides a forum for interdisciplinary publications combining mechanics with: Material science, Mechatronics, Biomechanics and Biotechnologies, Environmental science, Photonics, Information technologies, Other engineering applications. The journal publishes original papers covering a broad area of research activities including: experimental and hybrid techniques, analytical and numerical approaches. Review articles and special issues are also welcome. Following long tradition, all articles are peer reviewed and our expert referees ensure that the papers accepted for publication comply with high scientific standards. Engineering Transactions is a quarterly journal intended to be interesting and useful for the researchers and practitioners in academic and industrial communities.
