Description: This course covers the basics of the theory of structural dynamics. Free and forced vibration of damped or undamped single and multi-degree of freedom systems will be studied, which includes the response of single and multiple degree of freedom systems subjected to earthquake and other excitations with an emphasis on analysis and design of civil engineering structures. Course level: This course is a graduate level course but senior undergraduate students may take it by their advisor’s consent. Prerequisites: C or better in MATH 240 (Elementary Differential Equations) and ME 512 (Dynamics) and Structural Analysis Differential equations, linear algebra, mechanics of materials and matrix structural analysis. Some computer programming knowledge (e.g., in C, C++ or Fortran) or familiarity with software that requires less programming like Matlab, Mathcad, Mathematica, etc., is required for this course. Textbook: Anil K. Chopra, “Dynamics of Structures”, Prentice Hall, Second Edition, ISBN 0-13-086973-2 Additional Recommended Text: Leonard Meirovitch, “Fundamentals of Vibrations ”, McGraw Hill, ISBN 0070413452
Objectives and Outcomes: Objectives: Learning methods to analyze structures subjected to any kind of dynamic excitation and computing quantities like displacements, forces, stresses, etc. Understanding the analytical methods and procedures in a way that emphasize physical insight. Ability to apply the structural dynamics theory to real-world problems like seismic analysis and design of structures. Outcomes: At the conclusion of this course, the students will have an understanding of: fundamental theory of dynamic equation of motion fundamental analysis methods for dynamic systems dynamic properties and behavior of civil structures modeling approach of dynamic response in civil engineering applications At the conclusion of this course, the students will be able to: apply knowledge of mathematics, science, and engineering by developing the equations of motion for vibratory systems and solving for the free and forced response. create simple computer models for engineering structures using knowledge of structural dynamics interpret dynamic analysis results for design, analysis and research purposes apply structural dynamics theory to earthquake analysis, response, and design of structures Grading: Homework and Computer Assignments Midterm Final

Homework and Computer Assignment: Homework and computer assignments will be given periodically based on the materials covered. Each assignment will be related to the material covered within assignments. To learn the material in a course such as Structural Dynamics it is necessary to work all of the assigned homework problems and keep up to date. The concepts in this course are first learned and then applied to problem situations including the computer programs, which are the sole basis for assessment of the progress and achievement of students in this course. All examinations will be made up of problems that will require the application of principles and concepts by methods and procedures practiced in the class examples and homework assignments.
Exams: There will be 2 exams (One midterm and a final). The midterm exam will be announced at least one class period before the date of exam, and the final will be the first corresponding class session during the semester examinations period (Dec. 15 to 19). Solutions to exams are to be developed and presented in professional- manner. Partial credit will be assigned for incomplete and incorrect solutions only if they are presented in an orderly and logical fashion. Any grade is possible based on your understanding and knowledge. Class attendance and participation will help in some cases. Make -up Policy: There will be no make-up exam. Students who miss an exam by scheduling conflicts should make prior arrangements with me. Students who miss exams unexpectedly, but for a just cause will be given make- up exam. Students who miss an exam for unjust cause, based on my judgement, will not earn any grade for that exam. General Remarks: 1. Class time, and location, office hours and any other pertinent issue will be decided during the first week of classes. (First meeting on Monday August 25th ) Dates will be fixed afterwards except for unforeseen circumstances. 2. In case I miss an office hour due to unexpected circumstances, a message will be posted on the class web site with a reschedule time. So plan to check the online message board before coming to my office 3. Any important notice regarding the course will be sent to you by e-mail besides being posted on the course web site. So, please make sure that we have your correct e- mail address and check your e- mail every now and then.
