Automated Seismic Design of Reinforced Concrete Buildings
The report presents a new automatic method for the seismic design of reinforced concrete frame buildings. 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 method proposed herein aims for a uniform energy dissipation throughout the building frame, as measured by the individual member damage indices. The new damage index is modeled on the low-cycle fatigue phenomenon. The automatic design method is based on a thorough study of the effects of three important design variables, the longitudinal reinforcement, the 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 indices has reached a user-specified degree of uniformity. The usefulness of this design method, which incorporates aspects of a knowledge-based expert system, is demonstrated with a typical four-story three-bay office building.
