摘要

本文研究了不锈钢栓配不锈钢-木材组合剪力连接的力学性能。研究主要包括进行剪切推拔试验，以探索屈服形式、破坏模式以及螺栓直径、间距和木材厚度等参数对承载能力的影响。对中国标准GB 50005-2017、美国标准NDS-2018、欧洲标准Eurocode 5中剪力连接设计方法进行了评价。结果表明，GB 50005-2017、NDS-2018和欧洲规范5对不锈钢-木材剪力连接承载力的估计较为保守，而欧洲规范5的预测更为准确。此外，对Foschi和Hassanieh的两种分析模型进行了评估，并提出了新的输入参数，后一种模型在预测连接的载荷-滑移行为方面表现出更高的准确性。本研究结果有助于不锈钢-木材剪力连接的设计和建模，为未来在结构工程中的应用提供有价值的见解。

Experimental study on mechanical behaviour of stainless steel-timber composite shear connections

This study investigates the mechanical performance of stainless steel-timber composite shear connections equipped with stainless steel bolts. The research principally involved conducting shear push-out tests to explore the yield forms, failure modes, and the influence of parameters such as bolt diameter, spacing, and timber thickness on load-bearing capacity. The design methods for shear connections outlined in the Chinese standard GB 50005–2017, the American standard NDS-2018, and the European standard Eurocode 5 were evaluated. The results indicate that GB 50005–2017, NDS-2018 and Eurocode 5 provide conservative estimates of the bearing capacity of stainless steel-timber shear connections with Eurocode 5 offering more accurate predictions. Additionally, two analytical models, Foschi's and Hassanieh's, were evaluated and the new input parameters were proposed, with the latter model demonstrating superior accuracy in predicting the load-slip behaviour of the connections. The findings of this study contribute to the design and modeling of stainless steel-timber shear connections, providing valuable insights for future applications in structural engineering.

期刊介绍： Construction and Building Materials offers an international platform for sharing innovative and original research and development in the realm of construction and building materials, along with their practical applications in new projects and repair practices. The journal publishes a diverse array of pioneering research and application papers, detailing laboratory investigations and, to a limited extent, numerical analyses or reports on full-scale projects. Multi-part papers are discouraged. Additionally, Construction and Building Materials features comprehensive case studies and insightful review articles that contribute to new insights in the field. Our focus is on papers related to construction materials, excluding those on structural engineering, geotechnics, and unbound highway layers. Covered materials and technologies encompass cement, concrete reinforcement, bricks and mortars, additives, corrosion technology, ceramics, timber, steel, polymers, glass fibers, recycled materials, bamboo, rammed earth, non-conventional building materials, bituminous materials, and applications in railway materials.
