摘　　要：文章主要对木材—钢填板螺栓连接节点顺纹受拉时的承载力进行研究,针对5组不同螺栓连接类型的连接节点的承载力性能进行试验研究,并分析其破坏模式和破坏机理。螺栓连接节点的延性随着螺栓数量的增加逐渐降低。采用欧洲、加拿大、美国规范的有效螺栓节点数计算公式对螺栓节点进行理论计算,并对比各自的准确性。欧洲规范得到的理论值与试验值吻合度较好。The bearing capacity of bolted wood-steel-wood connections loaded parallel to grain is studied in this paper. Five groups of specimen with different connection type were tested to analyse the failure modes and failure mechanism. A decreasing ductility of joints was observed at the increase of the number of bolts. The effective number of fasteners was evaluated according to Eurocode,CSA ,NDS and compare with experimental resuits. Eurocode N.5 provide values for the bolt effectiveness quite closer to experimental results.
