Abstract: Building codes generally prescribe seismic design provisions that include a static lateral force procedure that can easily be combined with the gravity loads to design the structural elements. Although not always obvious to the engineer, the lateral force procedure has been developed to approximate the dynamic response that a building experiences during an earthquake. The distribution of the forces on the building approximates the effects of various modes of structural vibration. Special detailing requirements are used to supply ductility for excursions into the inelastic range of lateral movement. This paper gives background information on how buildings respond to earthquake caused ground motion and the relationship to the equivalent lateral force design code provisions.
