Experimental study on anti-collision device using titanium steel and recycle tires

Abstract

<p>Anti-collision devices can reduce the damage of bridge columns under ship collision, and a new device is proposed in the paper using a combination of titanium steel and recycle tires. The proposed device effectively improves the performance of buffering energy dissipation and durability under strong impact load. A 0.6 scale test specimen was designed and tested to investigate the behavior of the device under impact load; finite element models were conducted to analyze and compare with the experimental results. The performances of different types of the anti-collision device are compared, and the failure mechanism is studied.</p>
