摘要
本文讨论了铰接板梁桥的剪力铰强度。用能量方法推导了计算铰接力的正则方程和铰接缝强度的计算方法，并据此计算了两种跨度公路铰接空心板梁的铰接缝强度。计算结果表明：目前我国公路使用的某些铰接空心板梁的剪力铰强度不足，建议在规范中对剪力铰的强度计算加以适当规定。
The strength of shear pin the Shear-connected multibeam bridge was studled in this paper.By the use of energy principle,an equation calculating the shear force was deduced,And a calculation method of the strength of the pin was presented、Two examples were used to check the method. Results show that some shear-pin is unsafe under live load.
