Study of the resistance of bollards against impact loads

The objective of this study is to identify a simplified approach that can be used in the initial phases of the design process of bollards. Simplifications are proposed to evaluate a design without having to execute complicated numerical simulations or full-scale tests. For classical bollards, an analytical model is proposed, based on a simplification of the impact load. This analytical …
