《钢结构》中高强度结构钢高强度螺栓摩擦型连接抗滑移系数取值的探讨

Discussion on the Value of Anti-Slip Coefficient of High Strength Bolted Friction Connections of High Strength Structural Steel in Steel Structure

在钢结构的设计中,节点是保证钢结构安全的重要环节,而高强度螺栓摩擦型连接是钢结构节点连接的重要形式,其具有连接紧密、受力性能稳定、耐疲劳、可拆换、安装简单以及承受动力荷载时不易松动的优点。高强度结构钢在工程中的推广和应用,对连接的设计和应用提出了新的要求,需要发展新的计算理论和方法,而抗滑移系数作为计算承载力最基本的参数,它的取值是否合适直接影响计算结果的精确程度。本文通过调研相关文献的最新研究成果探讨了高强度结构钢抗滑移系数的取值,为土木工程专业钢结构课程的教学和钢结构设计提供一些参考。

In the design of steel structure, joint is an important link to ensure the safety of steel structure, and high-strength bolt friction connection is an important form of joint connection of steel structure. It has the advantages of tight connection, stable mechanical performance, fatigue resistance, removable, simple installation and not easy to loosen under dynamic load. The popularization and application of high strength structural steel in engineering put forward new requirements for the design and application of connections. New calculation theories and methods need to be developed. As the most basic parameter for calculating bearing capacity, the value of anti-slip coefficient directly affects the accuracy of calculation results. In this paper, the value of anti-slip coefficient of high strength structural steel is discussed by investigating the latest research results of relevant literature, which can provide some references for the teaching of steel structure course and steel structure design of civil engineering specialty.
