It identifies issues with current installations like collision This document presents the theory, methodology, and application for the design and analysis of both steel and concrete highway bridge superstructures. All components shall be finished as specified in 2. The bollard shall consist of three major assemblies: the sub-frame assembly, the bollard assembly, and the concrete foundation. As speed and mass increase, the likelihood and depth of penetration rise. The design evaluates a fixed circular steel bollard's ability to withstand a 5-ton Although bollards may be designed to be retractable, removable, or even decorative features (e.
