Abstract

Dynamic simulations of the behaviour of structures excited by natural or artificial diagrams are usually carried out by time history analysis with FE-methods which may include both geometric and material nonlinearities.

When a structure however during its response to seismic events may undergo significant changes due to large deflections, translations or rotations, the use of multibody dynamics may be preferable for simulating the structural behaviour.

An important case of a structural change may happen when a structure is base isolated or when uplifting, overturning or sliding effects may occur under seismic excitation.

The paper presents the basic equation of multibody systems for the simulation of such earthquake loaded structures and describes the computerprogram MEPHISTO that has been used to check particular systems that cannot be handled with other methods.
