摘要:
为了深入研究外伸端板连接设计方法,本文针对中美欧规范外伸端板连接设计方法进行了比较分析,总结了中美欧规范外伸端板连接设计方法异同.研究结果表明,中美欧规范均采用T型件设计理论对外伸端板连接进行设计,我国《钢结构高强度螺栓连接技术规程》(JGJ82-2011)和美国《建筑钢结构荷载抗力分项系数设计规范》(LRFD)在高强度螺栓连接技术规程中针对外伸端板的连接计算中均引入了破坏模式系数 α′ 以考虑T型件模型的三种破坏形式,欧洲规范EC3则直接按T型件的三种破坏形式进行计算.我国《钢结构高强度螺栓连接技术规程》(JGJ82-2011)针对高强度螺栓外伸端板连接节点首次引入了撬力设计方法,设计方法更加符合工程实际
Abstract:
In order to study the design methods of extended end-plate bolted connection, design methods end-plate connection according to JGJ82-2011, LRFD and EC3are compared and analyzed in the paper. Similarities and differences between the three are summed up. The results show that coefficientα′is introduced to consider three failure modes of T-stub both in design methods of end-plate connection according to JGJ82-2011and LRFD. But in the design method of end-plate connection according to EC3,the end-plate thinness and prying force is calculated directly according to three failure modes of T-stub. In“Technical Specification for High-strength Bolts Connection of Steel Structure”JGJ82-2011,design method considering prying force of end-plate connection is presented for the first time in China. The design method of extended end-plate bolted connection is more closed to the Engineering practices
