为了研究钢夹板—螺栓连接胶合木的抗剪性能,以东北落叶松胶合木—钢夹板螺栓连接件为研究对象,共设计12组(36个)钢夹板—螺栓连接胶合木进行剪切静载试验,结合理论分析和试验结果表明:材料规格和螺栓数目相同时,螺栓错列布置的抗剪能力明显高于并列布置;随着螺栓列数的增加,屈服荷载与极限荷载明显提高,且螺栓列数与剪切荷载呈非线性关系;在多螺栓连接件中,随着螺栓间距的增大,连接件的初始刚度与屈服后刚度呈减小趋势,极限荷载与屈服荷载呈增大趋势.

In order to study the shearing performance of steel splint-bolted glued wood, the paper designs 12 groups (36) steel splintbolted joint glued wood for shearing static load test with larch steel splint and bolted joint glued wood in northeastern China. Combined with theoretical analysis and experimental results, it is shown that the material specification and bolt number are simultaneously the shearing capacity of the bolt-column arrangement is obviously higher than that of the parallel arrangement; with the increase of bolt number, the yield load and the ultimate load are obviously improved, a...
