An Innovative Foundation System For Bollards and Barriers

A vehicular bollard is a barrier system used to restrict movement of vehicles around buildings. An important factor to consider in the design of bollards is the impact resistance of the bollard which is dependent on its foundation. Previous studies conducted on foundation systems for bollards mostly focuses on the use of shallow concrete foundation. However, a simple deep foundation technology can be employed for bollards with minimum cost. This thesis investigates the use of such deep foundation technology for bollards. Extensive experimental study into innovative foundation systems for vehicle bollards using soil was conducted in the laboratory to evaluate the performance of different pile systems under both static and impact lateral loads. The results demonstrated that part of the bollard can be used as a pile with fins attached on it to design simple deep foundation systems which are capable of resisting the vehicular load acting on the bollard.
