Three-dimensional dynamic analysis is required for a large number of different
types of structural systems that are constructed in Seismic Zones. The lateral force
requirements suggest several methods that can be used to estimate the distribution of
seismic forces within a structure. However, these guidelines are not unique and need
further interpretations. The major advantage of using the forces obtained from a
dynamic analysis as the basis for a structural design is that the vertical distribution of
forces may significantly be different from the forces obtained from an equivalent static
load analysis.
