Weblations. A new seismic zone (Zone 4) was added, representing active fault regions in California and Nevada. The base shear formula was modified by adding two new factors as follows: V = ZIKCSW (A.16) The new factor, I, is defined as an occupancy importance factor and is related to the potential hazard to life safety and varies between 1.0 WebDesign Base Shear Calculation The following equations are used to calculate the base shear force in the UBC 1997 seismic design process. Depending on the period of the structure, we have to calculate the Ft that will be applied at the top of the structure.
