Pipe Bollards
Pipe Bollards
(OP)
How do I determine the lateral force capacity of a concrete-filled pipe bollard, a section of which is buried in the ground?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: Pipe Bollards
1. Structural capacity of the pipe/concrete section assuming fixity in the ground.
2. Given the depth of embedment, determine the soil's lateral resistance to loading from the bollard.
The smaller of the two will prevail.
RE: Pipe Bollards
Typcially when a bollard is hit with sufficient force, the entire bollard tends to rotate and not bend if not designed as Ron suggests. To resist that kind of force, you would need excessive embedment in a concrete shaft.
You have to decide on your design criteria, whether to design as a freestanding cantilevered element capable of resisting an impact force; or to design as a sacrificial element.
