ABSTRACT

The purpose of this paper is to provide a better understanding of the behaviour of self-perforating dowels made of high-strength steel in CLT. The strength and stiffness of the connection is experimentally investigated and discussed, as are the influencing parameters. The results show the influence of the rope effect and drill tip on the load-carrying capacity of a connection with threaded dowels. Embedment tests revealed the analytical equations for embedment strength may overestimate results by up to 20%. In contrast, the analytical formula for the fastener’s yield moment may underestimate the real value up to 30% for high-strength steel dowels.

CLT中带有自穿孔定位销的开槽钢板连接的早期实验研究

抽象的

本文的目的是为了更好地理解CLT中由高强度钢制成的自穿孔定位销的性能。对连接的强度和刚度以及影响参数进行了实验研究和讨论。结果表明，绳索效应和钻尖对带螺纹销钉的连接的承载能力的影响。嵌入测试表明，嵌入强度的解析方程可能高估结果20％。相反，对于高强度钢销，紧固件屈服力矩的解析公式可能低估了高达30％的实际值。
