Designing a building so it can safely survive earthquake shaking without collapsing.
The engineering process of designing a structure to safely resist earthquake-induced ground motions. Seismic design considers the ground motion hazard at a site, the building's mass and stiffness, and the ductility of the structural system to prevent collapse during a major earthquake. Building codes classify structures by seismic design category and prescribe detailing requirements accordingly.
The hospital's seismic design uses a special moment frame and base isolation to protect life-safety systems during a major earthquake.
