What type of beams are you talking about?

Are you talking about concrete refilled fiber reinforced polymer tube systems?

 Are you talking about W-beams used in Guard Rail systems for Roadway applications?

As a some source information you my want to look at the reference below. It is a report from Texas A&M and the Texas Transportation Institute. It discuss the proper design of end treatment for guard rail systems.

Beyond that it appears that you are asking for specific Engineering Design recommendations, which is beyond the scope of Ask@engineer.com
