摘要

Two procedures are presented for seismic assessment of individual RC buildings on the basis of member seismic chord rotation demands. In the (simpler) "preliminary" evaluation procedure, inelastic chord rotation demands are estimated from linear analysis, while forces for brittle failure modes are computed in a capacity-design fashion. In the "final" or "detailed" evaluation, inelastic chord rotation demands and member shears are determined via nonlinear static (pushover) analysis. This procedure also requires more information on as-built materials and reinforcement. Verification criteria at three performance levels are proposed, tuned to be on the conservative side for "preliminary" evaluation.
