Abstract: Dynamic equations for seismic response analysis of foundation-structure system are derived from Lagrange equation. The analyses of complex seismic process and nonlinear dynamic characteristics, such as suddenly jumping and path effect of amplitude response, are made with catastrophe model. Some useful conclusions are drawn; and the analytic results are of good value to parameters design of foundation-structure system.

Key words: foundation-structure system, seismic response, catastrophe analysis, suddenly jumping
