抗拉剪摩擦型高强度螺栓连接的设计计算

THE DESIGN CALCULATION OF THE FRICTION-TYPE HIGH-STRENGTH BOLT CONNECTION TO RESIST PULLING FORCE AND SHEARING FORCE

为使抗拉剪摩擦型高强度螺栓连接的设计计算更趋合理、简便，分析了由弯矩作用引起的受压区板门压紧力变化对连接承载力的影响，提出了弯矩与剪力共同作用时和弯矩、轴力与剪力共同作用时的摩擦型高强度螺栓连接承载力的计算公式及其简化式．

In order to make that the design calculation of friction-type high-strength bolt connection is more reasonable and convenient,the author considered the influence of damping frce variation by momentcausing between the plates.The bearing capecity of the connection is analysed.The simplified formulae of the bearing capecity is given when the connection simultaneously subjected to moment and shear,and to moment,axial pulling force and shear.
