The relation between the lateral force design procedures presented in Seismic Design for Buildings TM 5-809-10 and those of more rigorous dynamic analyses are presented. It is noted in the paper that for the bulk of military structures, i.e., low, one- to three-story buildings, the design procedures given in the TM are valid. The limitations on the use of the TM and other similar codes are presented, particularly where functional considerations of the building are important. Trends in development of procedures for seismic design and buildings are discussed with emphasis on the response spectrum method. The conventional seismic coefficient method for the seismic design of concrete gravity dams is being supplemented by procedures coupling the computed dynamic response of the structure with the estimated future ground motion for the area. At present, both methods should be used to check the designs of new and existing hydraulic structures in high risk seismic zones. So far, precise standards have not been established for designating design earthquakes for an area or defining the requirements for a structures dynamic performance. This paper reviews the present earthquake design procedures, which involve computing inertial, hydrodynamic, and dynamic earth forces.
