Question:

How are steel rebars protected against lightning strikes?

Answer:

The process of "bonding" shields steel rebars from lightning strikes. When constructing a building, steel rebars are linked to a lightning protection system to safely redirect the electrical energy of a lightning strike into the ground. This system typically comprises lightning rods or air terminals positioned at the highest points of the building to attract the lightning strike. Subsequently, the rebars are interconnected with conductor cables, creating a network that effectively grounds the lightning current. The conductor cables are fastened to the lightning rods and extend down the building, connecting with the rebars at various points. By bonding the rebars with the lightning protection system, the electrical charge from a lightning strike is efficiently conducted away from the building and harmlessly discharged into the ground. Moreover, additional precautions such as surge protection devices are frequently installed to further safeguard the rebars and the overall building from potential damage caused by voltage surges resulting from lightning strikes. These surge protection devices assist in minimizing the risk of electrical surges that could potentially compromise the integrity of the rebars. To conclude, steel rebars are shielded against lightning strikes by establishing a proper bond with a lightning protection system. This ensures that the electrical energy from a lightning strike is securely directed away from the building and grounded, thereby reducing the risk of damage to the rebars and the overall structural integrity.

This ensures that the electrical energy from a lightning strike is safely directed away from the structure and grounded, reducing the risk of damage to the rebars and the overall structural integrity.
Steel rebars are typically protected against lightning strikes through the implementation of lightning rods or conductive bonding systems. These systems help to divert the electrical current from lightning strikes away from the rebars and into the ground, reducing the risk of damage or corrosion caused by the high voltage.
