... that the structure can be modelled as a space frame of three-dimensional beam elements connected by nodal points. If the structural system is assumed to be linear the dynamic equations may be written as M X+C x+K x=p(t) where x Displacement vector M C K p Structural mass matrix Structural damping matrix Stiffness...
