General Considerations for Seismic Stabilityby Lauren D. Carpenter, Skidmore, Owings & Merrill, Los, Angeles, CA, USA,
Abstract: The basic design consideration is provision of sufficient stiffness, strength and adequate ductility for the varied loads imposed on the building. Adequate stiffness is needed to resist building displacement during wind and moderate earthquake loadings, primarily in order to control damage to non-structural elements - and for taller buildings to mitigate perception of building sway during frequent wind storms. Secondly, adequate ductility is needed in the structural elements and connections as well as in the overall structural system to provide sufficient reserve of strength at large displacement to absorb severe earthquakes without building collapse.
