摘要
分析和研究了钢结构高强螺栓受拉连接采用外伸端板或T型接头的破坏机理、杠杆力产生的原因以及杠杆力的计算理论。介绍了我国《钢结构高强度螺栓连接技术规程》JGJ82征求意见稿中关于接头设计考虑杠杆力影响的设计方法。通过算例分析和比较了国内外几种高强螺栓节点连接考虑杠杆力作用的计算方法,为工程设计提供参考依据。
This article analyzes the failure mechanism for the tensile connection using high strength bolts with extended end plate or T-shaped steel and the causes of prying action. The connection design method considering prying action in "Technical specification for high-strength bolts connection of steel structure JGJ82" of China is introduced. Analyzing and comparing the difference of design method adopted by other countries on considering prying force in high strength bolt connection is presented and it provides useful reference for design of steel structures.
