The purpose of this course is to provide the student with an understanding of the response of structural systems to time-varying dynamic loads and displacements. The student will study the response of single degree-offreedom (DOF) and multi-DOF systems to harmonic and general loading conditions so that the theoretical bases of earthquake, blast, impact, and other structural loadings are understood. Solution methods for free vibration and forced vibration of single and multi-DOF systems will be studied. Response spectrum analysis for support excitation (earthquake motions) will be studied.
