EMTP Model of Anti-Earthquake Building Stroked by Lightning

This paper models an anti earthquake building during lightning stroke to the building. The transient voltages due to lightning of modeled building at the connection point between the building and ground base are investigated to study the effect of the connection wire between the building and grounding base of the building. Lightning current was injected into the vertical pillar A top of the building. The transient voltages due to lightning at the top of the building at vertical pillar A with roof connection and vertical pillar A with first floor connection were observed and discussed. The modeling for different cases and discussion show good results, and agree with the physical meaning of real cases. The maximum voltage at first floor depends on pillars base grounding resistance and connection wires. The effect of varying connection wire inductance for different grounding resistance on first floor maximum voltage show that as the connection wire inductance increases, the first floor maximum voltage increases.
