Equivalent viscous damping for buckling-restrained braced RC frame structures

While the direct displacement-based design (DDBD) method is commonly developed in seismic design of the single frame and is extensively discussed in the technical literature devoted to this subject, the proper evaluation of this method for dual frames system has received relatively little attention. Considering excellent hysteretic behavior, buckling-restrained braces (BRBs) have been increasingly configured in reinforced concrete (RC) frame to …
