38. Importance of Ductility
Ductility is a vital material property that enables structures to absorb energy and undergo plastic deformation without sudden failure, especially under seismic loads. It plays a crucial role in seismic design, distinguishing between structures that sustain and those that collapse during earthquakes. The emphasis on ductility enhances energy dissipation and redistributes forces, allowing for safer evacuation during seismic events.
