   The damper mega brace system adds an 8% supplemental damping that helps reduce both wind and seismic excitations. The system is made up of three braces in one (Fig. 6.31B): primary BRB brace and two external secondary BRB braces with viscous dampers at the ends (see Chapter 8, Section 8.1.10 for more details about this building).
