Abstract
I have developed a software called DSS which supports the sequence of operation of numerically solving the motion equation and displaying the analytical results graphically. DSS can deal with problems where the motion equation can be described in second order ordinary differential equation, with maximum of six analysis variables. DSS has four output ways of analytical result: GRAPH (a time history type), FFT (a frequency analysis type), ANIMATION (an animation type) and FREE (an optional type aiding users in completing their own program). Furthermore, a new function called MOVIE was added to DSS to be able to watch a real vibration phenomenon. In this paper, the outline of DSS is described first. Next, as an example, vibration phenomenon of three storey structure is simulated by using it.
