The Computation and Protection Research of Electromagnetic Field by Lightning Discharge on Metal Frame Buildings

摘要：

　　This thesis mainly introduces the variation characteristics of electromagnetic environment and the surface current when lightning struck on metal frame buildings with a case study of the Treasure Hall of Potala Palace.The simulated model of the Treasure Hall was constructed with the real scale and the same material properties.Then the effect of the lightning stroke on the metal frame are simulated by injecting the lightning current represented by the 10/350current waveform, the effect of the variation characteristics of the current flow through the metal surface and the external electromagnetic field can be dynamic displayed by using the probe or the reference plain.At last we can draw some valuable conclusions and preventing measures extract from the characteristics of fields.
