摘　　要：文章主要研究木材-钢夹板螺栓连接在顺木纹受拉时的承载能力。通过试验研究,对4组不同厚度木材共20个螺栓连接试件的结构性能进行了对比,同时深入研究了其不同破坏模式和破坏机理。木材-钢夹板螺栓连接的破坏模式、承载力大小及其延性性能均与连接中木材厚度的相对大小有关。木材-钢夹板螺栓连接在现代木结构中具有广泛的应用前景,其研究成果可为我国现代木结构的加工、设计和应用提供参考。The bearing capacity of bolted steel-wood- steel connections loaded parallel to grain is studied in this paper. Four groups, which have a total of 20 specimens, were tested to failure. Comparison on the structural behavior was developed. Then the failure modes and failure mechanism of the bolted connections were discussed in detail. For bolted steel-wood-steel connections, the failure modes, bearing capacity and ductility are relative to the thickness of wood members. Bolted steel-wood- steel connections have a good prospect in the modem timber structures. The whole work can be taken as a reference of manufacture, design and application of modem timber structures.
