thirds of the Maximum Considered Earthquake (MCE) shaking level.
In the usual application, two sets of earthquake ground motions are selected, one to represent an a service level eartquake earthquake (SLE) and and another to represent an a maximum considered eartqauke earthquake (MCE). Calculated responses include maximum transient and residual displacements and story drifts; inelastic rotations and strains in components that are intended to yield as part of the inelastic mechanism; and internal forces in components or in behaviors that are intended to remain within the linear-elastic range of response. Each ground motion produces its own response, requiring a statistical evaluation of the results to determine whether the structural system meets the performance criteria.
