采用8组40个连接试件,考察胶合木外夹钢板群螺栓连接构件在顺纹受拉时的力学性能,探讨其破坏模式和受力机制。研究表明：胶合木外夹钢板群螺栓连接的破坏模式、承载力、刚度和延性与螺栓列数、每列的螺栓数、螺栓的布置方式有关;承载力不具有由螺栓数线性叠加的性质;螺栓总数不变、多列布置螺栓延性较佳。

英文摘要：

The mechanics performance of multi-bolt steel-glulam-steel joints subjected to a load parallel to grain was investigated with 8 groups of 40 multi-boh joints specimens. The failure mode and its mechanism were discussed. For multi-bolt steel-glulam-steel joints, results showed that the failure modes, bearing capacity, stiffness, and ductility were relevant to the rows of bolts, the number of bolts in a row and the way of bolts arranged. The bearing capacity of multi-bolt joints was nonlinear number of bolts. With the same number of bolts, the ductility of bolts arranged in multi-rows was better than that of one-row.
