1994 Triggered Lightning Test Program: Measured responses of a reinforced concrete building under direct lightning attachments

PDF Version Also Available for Download.

Description

A rocket-triggered lightning test was carried out during the summer of 1994 on a specially designed steel reinforced concrete test building located at Ft. McClellan, Alabama. Currents, voltages, and magnetic fields were measured at 24 instrumented locations during 42 return strokes triggered to designated points on the structure and its lightning protection systems. As was found during an earlier similar lightning test of an earth covered munitions storage building, the buried power service conduits carried a much larger fraction of incident stroke current away from the building than did the intended grounding elements of the lightning protection system. Electrical breakdown ... continued below

Description

A rocket-triggered lightning test was carried out during the summer of 1994 on a specially designed steel reinforced concrete test building located at Ft. McClellan, Alabama. Currents, voltages, and magnetic fields were measured at 24 instrumented locations during 42 return strokes triggered to designated points on the structure and its lightning protection systems. As was found during an earlier similar lightning test of an earth covered munitions storage building, the buried power service conduits carried a much larger fraction of incident stroke current away from the building than did the intended grounding elements of the lightning protection system. Electrical breakdown and subsequent arcing occurred repeatedly to create dominant current paths to earth that were not accounted for in pretest linear modeling. Potential hazard level transient voltages, surprisingly more resistive than inductive in nature, were recorded throughout the structure. Also surprisingly, strikes to a single grounded protection mast system resulted in internal environments that were generally comparable to those occurring during strikes to roof-mounted air terminals. A description of the test structure, experimental procedures, and a full set of the resultant data are presented in this two-volume report.
