In the connection design of steel structure, the shear plate with high-strength bolt connection is extensively used at the flexible joint where the beam is connected to the weak axis of the column.
The results show that proper pressure and interlayer thickness can evidently improve the microstructure and mechanical properties, and the shear strength of joint is increased with the holding time.
结果表明：合适的压力和中间层厚度能有效改善接头的组织和力学性能，接头剪切强度随保温时间延长而提高。

To overcome the shortcomings of the shear pin type joint and left-hand thread type joint, a sliding sleeve subsurface safety joint is developed.
