Elastoplastic, plastic analysis. Equivalent systems, dynamic hinge concept. Modal analysis. Transfer matrices. Fourier, Laplace transforms. Prerequisites Dynamics (4600:203) or equivalent. Theory of Structures (4300:306) or equivalent. Course Overview This class is offered as a traditional face-to-face class OR as an online class. The online teaching experience is different from that of teaching a traditional face-to-face classroom. As a student in this class, you are required to log into Springboard several times each week to find the latest updates for class, participate in discussions if you are having difficulty or can help another student, and submit your work (if you would prefer online submission to in-class submission). This course is supported by The University of Akron s course management system called Springboard. If you are new to Springboard, you can get started by watching the tutorials here: Course Objectives After completing this course, you will be able to: 1. Calculate the free-vibration response of single-degree-of-freedom (SDOF) systems. 2. Calculate the forced-vibration response of SDOF systems to several types of excitations. 3. Express a rigid or distributed dynamic system as an SDOF system. 4. Identify dynamic degrees of freedom (DOFs) in multi-dof (MDOF) systems. 5. Calculate the free-vibration response of MDOF systems.

The biggest difference is that you will be responsible for your own time management and organization. This requires discipline and attention to detail. The role of your instructor in an online course is to make the information for learning available to you and your role is to follow through with the structures put in place to help you learn. You must read all directions, follow all calendars, and ask questions when you are unsure of what to do. You need to log into the course and check your university on a regular basis, daily is best, to ensure that you have the most up to date information. You need to locate and understand all instructions, follow through on all assignments, and stay on track with due dates. You are also responsible for the technical requirements necessary for your course. This means that if you have computer or connectivity problems you are not guaranteed an

3 extension; you must have backup systems available at all times. The University Library is always available to you, and technical support is only a phone call away. All assignments are due at 11:59pm on the due date posted on the assignment sheet. Electronic submissions may be made in the appropriate Springboard dropbox folders. Etiquette Online etiquette, sometimes called Netiquette, requires special attention because it lacks the visual cues that we rely on to give meaning to communication. 1. Avoid language that may come across as strong or offensive. Language can be easily misinterpreted in written communication. If a point must be stressed, review the statement to make sure that an outsider reading it would not be offended; then post the statement. Humor and sarcasm may easily be misinterpreted as well, so try to be as matter-of-fact and professional as possible. 2. Keep writing to a point and stay on topic. Online courses require a lot of reading. When writing, keep sentences poignant and brief so that readers do not get lost in wordy paragraphs and miss the point of the statement. Also, do not introduce new topics; it may just confuse the readers. 3. Read first, write later. It is important to read all posts or comments of students and instructors within the course discussion before personally commenting to prevent repeating commentary or asking questions that have already been answered. 4. Review, review, then send. There s no taking back a comment that has already been sent, so it is important to double-check all writing to make sure that it clearly conveys the exact intended message. 5. An online classroom is still a classroom. Though the courses may be online, appropriate classroom behavior is still mandatory. Respect for fellow classmates and the instructor is as important as ever. 6. The language of the Internet. Though still a fairly young type of communication, certain aspects of this form of communication are becoming conventional. For example, use appropriate capitalization (e.g., do not write using exclusively capital letters or exclusively lowercase letters). Also, the use of emoticons can be helpful when used to convey nonverbal feelings [ for example, :-) or :-( ], but avoid overusing them. 7. Consider the privacy of others. Ask permission prior to giving out a classmate's address or other information. 8. If possible, keep attachments small. If it is necessary to send pictures, change the size to an acceptable 100k. To attach a copy of your work, please scan the papers to a reasonable resolution (e.g., 200ppi) and upload a PDF. 9. No inappropriate material. Do not forward virus warnings, chain letters, jokes, etc. to classmates or instructors. The sharing of pornographic material is forbidden.

You are responsible for clearly labeling your papers so I can identify your submission. For example, use your first and last name in the filename along with the assignment number. You are also responsible for submitting files in formats that I am able to open (e.g., *.pdf, *.doc, *.docx, *.xls, *.xlsx, or *.xmcd). Note that the University provides a Google Apps account to all students. You can use Google Apps to create files in these filetypes. Additional software you may need is posted here: You are responsible for maintaining copies of your work and verifying that your Dropbox submission has been received. You will receive an confirmation when you submit assignments. You will be also able to track your submissions in Springboard. You are responsible for completing all assignments and exams before the due dates.

5 Technical challenges are not an acceptable excuse for missing deadlines. You must ensure that you have access to a working computer at all times. Please do not wait until the deadline to submit assignments. If you do experience any technical issues, please contact Zip Support and ensure that the issue is tracked though the Footprints ticketing system. If you have any questions or concerns about any of the assignments or your performance, please contact your instructor immediately. Do not wait until the assignment is due or the problem cannot be rectified. Withdrawal Policy Starting in Fall 2011, The University of Akron has revised its rules for dropping or withdrawing from a course. The official University Policy (Revised in Fall 2011) is as follows: For graduate and undergraduate students: A student may drop a course through the 15th calendar day of a semester or proportionately equivalent dates during summer sessions, intersession and other course terms. A "drop" will not appear on your transcript. The class simply "disappears." After the 15 calendar day period, students may withdraw from a course through the 49th calendar day of a semester or proportionally equivalent dates during summer session, intersession, and other course terms. If you withdraw, a "WD" will appear on your transcript. You should know that a withdrawal may affect your financial aid, eligibility for on-campus employment and eligibility for insurance. Speak with your adviser for details. A student who leaves a course without completing the coursework and without going through the withdrawal procedure will be given an "F" in the course. To process a drop or withdrawal from a course, access Zipline. No signatures are required. Questions regarding your registration can be addressed by the Office of the Registrar, , The Withdrawal Policy is located here: Incompletes Incompletes indicate that the student has completed passing work but that some part of the work is, for good and acceptable reason, not complete at the end of the term. Failure to make up the omitted work satisfactorily by the end of the following term, not including summer sessions, converts the "I" to an "F." When the work is satisfactorily completed within the allotted time the "I" is converted to the grade that the student has earned. Student Ethics Academic Honesty Students at The University of Akron are an essential part of the academic community, and enjoy substantial freedom within the framework of the educational objectives of the institution. The freedom necessary for learning in a community so rich in diversity and achieving success toward our educational objectives requires high standards of academic integrity. Academic dishonesty has no place in an institution of advanced learning. The University community is governed by the policies and regulations contained with the Student Code of Conduct available in the Office

6 of Student Judicial Affairs, Student Union 216, (330) , Syllabus The University of Akron considers academic integrity an essential component of each student's personal and intellectual growth. Instances of academic dishonesty are addressed consistently. All members of the community contribute actively to building a strong reputation of academic excellence and integrity at The University of Akron. It is each student's responsibility to know what constitutes academic dishonesty and to seek clarification directly from the instructor if necessary. Examples of academic dishonesty include, but are not limited to: Submission of an assignment as the student's original work that is entirely or partly the work of another person. Failure to appropriately cite references from published or unpublished works or print/non-print materials. Unauthorized copying of an assignment in computer programming, or the unauthorized examination or view of the computer, specifically during examinations. Possession and/or unauthorized use of tests, notes, books, calculators or formulas stored in calculators not authorized by the instructor during an examination. Providing and/or receiving information from another student other than the instructor, by any verbal or written means. Observing or assisting another student's work, when not part of a group activity. Violation of the procedures prescribed by the professor to protect the integrity of the examination. Cooperation with a person involved in academic misconduct. Submitting the same assignment in two different classes Plagiarism and Academic Integrity The following University of Akron, University Libraries website is an excellent source to help you, the student, understand plagiarism and how to avoid it: It is also an excellent resource for you as a future trainer. A student who has been accused of academic dishonesty will be asked to meet with the course instructor. The matter can be resolved informally at the College level and/or an academic sanction can be imposed. If the student opposes the decision, he/she may appeal to the College Dean. If the matter is referred to the Office of Student Judicial Affairs, an informal meeting will occur and, if substantial evidence exists, the office has the authority to take formal action against the student including, but not limited to, suspension or dismissal from the University. A more detailed discussion of these procedures can be found in the Student Code of Conduct:
