Design Guidelines for Ductility and Drift Limits (Parts A-D)

This project was concerned with the development of approaches that can be utilized to
determine the drift and ductility demands and capacities for high-rise buildings and to
improve seismic design practice through the explicit incorporation of ductility and drift
control in the preliminary design process. To achieve this objective, emphasis was placed
on (a) a review and evaluation of the state-of-the-practice in ductility and drift based
earthquake resistant design, (b) an evaluation of the damage potential of recorded ground
motions, (c) in-depth studies of the seismic performance of three high-rise reinforced
concrete frame buildings, including accurate analytical modeling, nonlinear time-history
analysis, assessment of predicted and recorded responses, and evaluation of detailing, (d) a
study of member detailing requirements, and (e) the development of a conceptual design
approach.
