For most seismic braced frames, strength rather than stiffness governs design. Still, it is important for designers to understand braced frame drift and predict inelastic [...]

Buckling-restrained braced frames (BRBFs) are used in steel buildings to resist lateral earthquake loads. The system ductility of typical BRBFs is limited by the performa [...]

In steel buildings, all columns of a story experience similar drifts under seismic loads when floor diaphragms are rigid. Columns in lateral-force-resisting frames are de [...]
