Abstract:
Presents an automatic method for seismic design of reinforced concrete frame buildings, which aims for a uniform energy dissipation throughout the building frame, as measured by the individual member damage indexes. A new damage index is briefly reviewed, which serves as a measure of a member's residual energy dissipation capacity, and thus is suitable as a control parameter in an automated design method. The design method is based on an extensive study of the effects of three important design variables: longitudinal reinforcement, confinement steel, and member depth. Design rules derived from the large number of numerical studies allow an iterative improvement of a preliminary design until the distribution of damage indexes has reached a user-specified degree of uniformity.
