摘要
对4组不同木材厚度共20个螺栓连接试件的结构性能进行试验研究,得到木材-钢填板螺栓连接在顺纹受拉时的承载能力,并探讨其破坏模式及破坏机理.研究表明,木材-钢螺栓连接的破坏模式、承载力大小及其延性均与连接中侧材相对厚度有关.木材-钢螺栓连接在现代木结构中具有广泛的应用前景,研究结果可为我国现代木结构的加工、设计和应用提供参考.
Four groups having a total of 20 specimens, were tested for its structural performance. The bearing capacity of bolted wood-steel-wood connections loaded with the grain was obtained. Then the failure modes and failure mechanism of the bolted connections were discussed in detail. For bolted wood- steel-wood connections, failure modes, bearing capacity and ductility relates to the relative thickness of the side wood members. Bolted wood-steel-wood connections have a good prospect in modern timber structure application. The result can provide a reference for design, manufacture and application of modern timber structures.
