These definitions are obtained from FEMA P-749, but are very close to the brief descriptions in ASCE/IBC procedures. Forces to be applied at each floor level can be calculated as follows. 4) Definitions of seismic design categories is shown in Table 7. SAMPLE DESIGN CALCULATIONS. However, from a seismic design point of view, several other design … 3) Seismic design categories (_____) can be assigned and determined as a function of the “mapped” spectral accelerations and the risk category.
