Studies were conducted at the University of California to design, construct, and test the largest possible model of the full-scale test structure that could be accommodated on the earthquake simulator at the University of California, Berkeley. The model was designed to comply with the similitude requirements for a reduced-scale model. Since the reduced-scale structural shapes were not commercially available, all the members were fabricated from steel plates. The details of the study are described, and the conclusions drawn are presented, that are valid for the 6-story concentrically braced model tested. Extrapolation of the results to other concentrically braced dual steel systems are possible under certain conditions. It was found that the concentrically chevron-braced dual system can provide sufficient elastic stiffness to avoid structural and non-structural damage during minor earthquake shaking. The addition of the braces increased the lateral stiffness of the dual system to a value of about 3.9 times the lateral stiffness of the basic DMRSF (ductile moment resisting space frames). These and other findings are set forth.
