Earthquakes can be so destructive to structures and societies. This video explains what we have learned about them and how engineers deal with the enormous seismic forces. The key concept in seismic design is to allow damage to be sustained by the structure. The cracking of concrete, yielding of steel, or snapping of bolts and fasteners requires input energy. This energy comes from the earthquake and is dissipated when the damage occurs.
However, if the structure is not designed properly this damage could cause a complete collapse. Therefore, it is crucial to provide a ductile design that could sustain a lot of damage before the structure loses its capacity to maintain its gravity loads.
