Earthquake or seismic performance defines a structure's ability to sustain its main functions, such as its safety and serviceability, at and after a particular earthquake exposure. A structure is, normally, considered safe if it does not endanger the lives and well-being of those in or around it by partially or completely collapsing. A structure may be considered serviceable if it is able to fulfill its operational functions for which it was designed.
Basic concepts of the earthquake engineering, implemented in the major building codes, assume that a building should survive a rare, very severe earthquake by sustaining significant damage but without globally collapsing . On the other hand, it should remain operational for more frequent, but less severe seismic events.

Famous quotes containing the words seismic and/or performance:
“Most near, most dear, most loved and most far,
Under the window where I often found her
Sitting as huge as Asia, seismic with laughter,”
—George Barker (b. 1913)
“Tennis is more than just a sport. It’s an art, like the ballet. Or like a performance in the theater. When I step on the court I feel like Anna Pavlova. Or like Adelina Patti. Or even like Sarah Bernhardt. I see the footlights in front of me. I hear the whisperings of the audience. I feel an icy shudder. Win or die! Now or never! It’s the crisis of my life.”
—Bill Tilden (1893–1953)
