The Design for Disaster Defense:

What are the 3 main pillars of seismic-resistant structures? They are strength, stiffness, and ductility. The structure must be strong enough to withstand the maximum forces induced by the seismic environment. As a result, the lateral load-resisting system must have adequate stiffness to contain drift within the prescribed limit. Finally, it must be ductile enough to mobilize such deformation.
