AbstractThe basis of design and the seismic load, including the factors that contribute to the base shear calculation, e.g. seismic zoning, seismic spectral content, period determination, structural behaviour, importance factor and soil/foundation factor, are examined. The method of distributing the forces in the vertical direction, torsion, storey drift limitation, etc. are also presented. Similarities and differences among the three codes are noted. It is found that, in general, the provisions of the three countries can be related to one another in terms of the various components. The base shear in the respective highest seismic zone is largest in the Japanese code (BSLJ) and lowest in the NEHRP recommendations of the U.S.A.; seismic forces in the Canadian code (NBCC) fall slightly above those of NEHRP.
