Structural Effects of a Lightning Strike
Structural Effects of a Lightning Strike
(OP)
Does a lightning strike apply any additional forces to a structure?
I have done some research on this and have come across: "Any conductor carrying lightning current will be subject to an electromagnetic force F=Bli in Newtons."
B = the component of the magnetic field at right angles to the conductor
l = length of the conductor (meter)
i = the current (ampere)
Would this be the only force applicable? Is there another known way to quantify this? We are designing a tall structure and want to ensure there are no additional loads from a lightning strike that would affect the structure, even though we can't imagine it would be enough to even consider.
Thank you!

They pulled out long lengths of wire, and 30' down the wall was where it found an easier path and blew the insulation off, and arced a hole in the water line.
