ASCE 7-16 recommends that a standart building be designed to satisfy one performance objectives, life safety it has been subjected to two-third of the Maximum Considered Earthquake (MCE) shaking level.
In the usual application, two sets of earthquake ground motions are selected, one to represent an service level eartquake (SLE) and another to represent an maximum considered eartqauke (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.
