Recognition of larger building motions caused by earthquakes spotlights exterior wall connections
Seismic design provisions for buildings have in extent relied on the understanding that building frames that are more ductile, and thus deform well beyond the usual "elastic" limits used in engineering design, perform better than buildings that are "brittle."
This opinion was strengthened by way of the unanticipated poor performance of steel-framed buildings with brittle welded importance connections during the 1994 Northridge earthquake in the beholds Angeles area.
