Web based e-learning system is developed for the education of structural dynamics for University students and for the dissemination of disaster prevention for the society people. This system shows the dynamic response of the 2-dofs lumped mass system. It is possible to easily make a virtual experiment on a web browser. User can produce the seismic ground motion by dragging the ground with the mouse right and left on the browser. The ground can also be shaken by the observed earthquake wave in the database. User can freely make an experiment using various variables. The students easily understand the dynamic phenomena of structure through the combination of formulation, graph, and the experiments using this software.
