How must strike termination devices be connected to structural steel framing?

Strike termination devices must be connected to structural steel framing in a manner that ensures an effective path for lightning strikes to reach the ground without causing damage or hazards to the structure. The chosen method of connection can vary based on the specific installation and design requirements, but there are several accepted practices.

A direct connection provides a straightforward and reliable path for the lightning current to flow into the steel framing and down into the grounding system. This method is often favored for its simplicity and efficiency.

Using an external lightning conductor can also be a valid approach. This method can help direct the lightning strike away from the structure and guide it safely to the ground, reducing the risk of damage to the building and its occupants.

Individual conductors running through the roof are another viable option. This setup can allow for flexibility in the installation and can be used in conjunction with other protective measures, ensuring each individual termination device is properly bonded to the structural steel.

Since all these options are acceptable ways to ensure effective grounding and protection from lightning strikes, the conclusion is that any of these methods may be utilized appropriately based on the specific requirements and characteristics of the structure and its environment.
