Metal Building Systems Performance in Ground Motion Events

“…. Preliminary results suggest that metal building systems generally have a high level of system overstrength and will perform excellently under the most demanding ground motions.”

Paraphrased from the below article: “Three Metal Building System specimens were tested to determine the seismic response of various configurations. Each specimen was subjected to a series of ground motions with increasing magnitude until the specimens were damaged to a state which precluded further testing. Although it is thought that metal buildings lack ductility, preliminary results suggest that metal building systems generally have a high level of system overstrength and will perform excellently under the most demanding ground motions.”
