DOI: 10.1007/s00158-021-02965-5
Abstract: In this study, the optimal seismic design of traditional and buckling-restrained braces (BRBs) 3D-reinforced concrete (R/C) buildings is compared. The optimal buildings are obtained through the non-dominated sorting genetic algorithm (NSGA-II) multi-objective technique. Unlike most… read more here.

DOI: 10.1016/j.engstruct.2021.112018
Abstract: Abstract As a high-performance hysteretic damper, buckling-restrained braces (BRBs) can significantly improve the seismic behavior of engineering structures and protect the main building components from damage. However, the complex BRB-to-reinforced concrete (RC) member connection is… read more here.
