The shearing angle is adjustable, to minimize the distortion of sheet bar.
剪切角可调，减少板料扭曲变形；

The testing results about the use of new rail joint was introduced, which include the dynamic flexure stress of upper limb and lower margin of joint bar, shearing stress of horizontally neutral axis.
The transfer of shearing and moment must be considered in dynamic analysis because the model of dowel bar affects the modal frequency and modal shape directly.
