Truss frame generally have to be designed elastically even against large seismic force, because of fragile characteristics led by member buckling. However, designing truss structures elastically against large earthquake is not economic, not elegant in design, and remaining risks for fragile collapse in the event of seismic level exceeding the design criteria. In this paper, damage controlled design for truss frame structures using energy dissipation members in critical positions are discussed. A detailed design applying this concept to space truss roof for school gymnasium is studied, and their performances and simple estimation methods for seismic response are discussed.
