Structural Optimization for Stiffness and Ductility of High-Rise Buildings

Several practical tools for the characterization of the optimal layout of material in a structure have been developed in recent years based on both numerical and analytical approaches. Within the analytical methods, optimal layouts can be based on specific geometric rules recently investigated in the literature. The resulting designs represents a stiff structure which requires ductile elements placed at strategic locations to minimize the impact of an extreme seismic event on the structure itself. This presentation will highlight a methodology to combine stiff optimal geometrical layouts with the use of ductile links in a high-rise building.
