木结构螺栓连接的力学性能研究进展

Reviews of Mechanical Properties for Timber Bolted Joints

螺栓连接已广泛用于现代木结构建筑中,系统研究其力学性能对建筑结构的安全性评估意义重大。本文从螺栓连接强度的预测方法、力学行为模拟、螺栓预紧、螺栓连接的破坏方式,以及抗火抗震条件下的力学性能等方面进行了总结归纳,针对目前的木结构螺栓连接中尚未解决的问题及有待进一步开展的研究项目,建议加强复螺栓连接的力学行为模拟、可靠性评价等研究。

Bolted connections have been widely used in modern timber structures. Their mechanical properties are very important for designing safe and durable wood structures. The authors have summarized studies on timber bolt connections for predicting failure, as well as modeling strength and mechanical behaviors under fire and seismic conditions. The authors also have made some suggestions for future modeling mechanical behavior and reliability based on previous development in modern timber bolted joints.
