Revision The first edition is ISO3010 : 1988 “Basis for design of structures – Seismic actions on structures”, canceled and replaced by the second edition ISO3010:2001(E).
Horizontal Base Shear

 

 VE : Base shear force for ultimate limit state or serviceability limit state

          W : Total weight of the building
         γE  : the load factor as related to reliability of the structure informed
                    in Table 1
          kZ : seismic hazard zoning factor
          kE : representative value of earthquake ground motion intensity
                  informed in Table 1
          kD : structural factor as related to ductility, acceptable deformation
                 and restoring force characteristics, and also related to
                 overstrength of the structure informed in Table 2
          kR : normalized design response spectrum (Fig. 1)          

： ( = kRO : recommended)
：
： (≥ [1/3 to 1/5]･kRO : recommended)

          T : the fundamental natural period of the structure
           kR0 : a factor dependent on the soil profile and the characteristics of
                    the structure, e.g. the damping of the structure; for a structure
                    with a damping ration of 0.05 resting on the average quality
                    soil, kR0 may be taken as 2 to 3.
          TC & T'C : values from table 3
          η: an exponent that can vary between 1/3 to 1.
