The results show that the shear stress increases as the rising of the particle volume fraction, and the shear stress is proportional to the square of the magnetization.
By adopting square rod support instead of the round rod support, the shear action between the pipe bundle and support structure can be reduced at a high degree.
把杆式支撑结构中的圆杆支撑改为方杆支撑，很好地减小管束与支撑结构间的剪切作用。

The shear bond strength of circular CFST is great than the square one, and is not considerably affected by the concrete strength.
