A truss for use in building construction having a center portion adapted to "go plastic" during a seismic event, and two outer portions at opposite ends, which remain inelastic during such event. The center portion features spaced opposed upper and lower C-channels connected to interposed spaced gussets, which gussets are connected by both vertical angle members and crossed bars. The crossed bars are also connected at their midpoints to a connection plate.
