Summary

Braced frames offer high strength and stiffness, but greater stiffness can lead to poor seismic performance due to increased forces. Despite this, braced frames can be economical in seismic regions. The intended function of a braced frame is to resist lateral forces through axial actions, with ductile behavior achieved through buckling and yielding. However, conventional brace elements can be problematic under strong ground motions, leading to a dramatic drop in stiffness and strength. Eurocodes attempt to address this issue by balancing demand-to-capacity ratios and limiting over-strength. Alternative devices, such as buckling-restrained braces, have been developed to resist and dissipate seismic forces, offering improved performance and equal properties in compression and tension.
