为深刻认识装配式木结构钢夹板螺栓连接的抗剪性能,准确计算其抗剪承载力,针对装配式木结构中胶合木-钢夹板螺栓连接件的构造特点,考虑胶合木厚度与螺栓直径之比(厚径比)、螺栓间距及螺栓并列、错列布置3个因素的影响,设计了3类17组共51个推出试件,并进行了纵向荷载作用下胶合木-钢夹板螺栓连接件的抗剪性能试验.采用推出试验与有限元数值模拟相结合的方法,探讨了胶合木-钢夹板螺栓连接件的剪切破坏机理和螺栓垫片对其抗剪性能的影响.结果表明:胶合木-钢夹板单螺栓连接中,随厚径比的增大,螺栓连接的破坏模式逐渐由“单铰”向“双铰”转化,最佳厚径比为7.5;在多螺栓连接中,螺栓从上至下的弯曲程度...

To understand the shear performance of bolted connections with steel plates in assembled timber structures and accurately calculate the shear capacity, specimens were designed according to the structural characteristics of glued laminated timber connections with steel plates. At the same time, considering the effect of the ratio of timber thickness to bolt diameter, bolt spacing, and bolt arrangement in parallel or staggered formations, the shear behaviors of glued laminated timber connections with steel plates were tested. In this study, 51 sp...
