Seismic Analysis Using Three Dimensional Modeling


AbstractThree-dimensional dynamic analysis is required for a large number of differenttypes of structural systems that are constructed in Seismic Zones. The lateral forcerequirements suggest several methods that can be used to estimate the distribution ofseismic forces within a structure. However, these guidelines are not unique and needfurther interpretations. The major advantage of using the forces obtained from adynamic analysis as the basis for a structural design is that the vertical distribution offorces may significantly be different from the forces obtained from an equivalent staticload analysis.
