摘　　要：介绍了三种半刚性连接弯矩—转角关系曲线数学表达式,阐明了实用的三折线表达式用以描述高强螺栓端板连接的弯矩—转角关系,通过对比分析证明了该三折线表达式做出的曲线可以比较准确地预测高强螺栓端板连接节点的弯矩—转角变化趋势,为相关节点设计提供了有益参考。By the introduction of three types of mathematic expressions describing the moment-rotation （M-θr） curve of semi-rigid connections, a practical trilinear expression was given to describe the relationship of the M-θr curve to the high-strength bolt （HSB） end-plate connections. The M-θr curves were drawn according to trilinear expression, which can forecast the variation tendency of the M-θr of HSB endplate connection joints relatively well by comparison with experimental curves and can provide a good reference for the design of relevant joints.
