Historically, rockfall barrier post support consisted of a small concrete block (generally 1 yd) often without reinforcement. Field experience with these foundations was very good, and showed acceptable performance even during significant and beyond-design energy impacts. Recently, post support design has changed. Much larger foundations are used, as a result of designers needing to design even more massive foundations in order to provide something that would satisfy the foundation’s loads provided by barrier manufacturers.

In the absence of industry-specific post support methodologies and guidelines, designers have been forced to design according to standards that do not apply to the performance needed from a rockfall barrier post support.
