Understanding Structutul Ductility

Structural ductility refers to struktur 's ablity to undergo deformation without losing its load- carrying capacity. Ductile structures octile sumbure and disgrate energy during an earthquake, reduccino hnus oddeun falurre.

Energy Dissipation Mechanisms

Energy dispastion involves inserbing seistimic energy to reduce forces the transmitted to the structures. Common mechanisms inclutendde plastic hinges, dampingg devices, and base isolator.
