CE 725 – EARTHQUAKE STRUCTURAL ENGINEERING
COURSE OBJECTIVE
At the conclusion of the course, students will (1) Develop an understanding for the effects that
earthquakes have on structural systems and the importance of ‘Capacity Design’. (2) Develop
an understanding of basic aspects critical for seismic design, assessment, retrofit, and
modeling. (3) Apply the basic principals of Performance-Based Earthquake Engineering,
through the use of Direct Displacement-Based Design, to a variety of structural systems.
PREREQUISITES
Structural Dynamics (CE 527 or equivalent). Courses in structural design (concrete) helpful.
TEXT
Displacement-Based Seismic Design of Structures. M.J.N Priestley, G.M. Calvi, and M.J.
Kowalsky. IUSS Press, 2007. Available online via the IUSS press at:
http://www.iusspress.it/pc/viewCategories.asp?idCategory=21&lvl1=17
Also available via the NCSU bookstore.
NOTE: I will place a group order for books for interested students at the start of the semester.
This will result in significant savings as shipping costs and book costs reduce with increasing
numbers of books.
GRADING
Homework – 40% (8 Assignments) NOTE: While I encourage you to discuss concepts and
homework in groups if you like, all homework assignments must be done individually,
and be unique to each student.
Final Exam - 50%
Journal and Text Readings – 10% (2 Research Article Reviews; 6 Text Summaries)
Final grades are obtained based on a relative scale with the course average in the B+ range. In
the past, the course average has varied from 87% to 89%.
LECTURES
Tuesday and Thursday, Location Withers 125: 10:15am-11:30am. The only electronic device
to be used in class is your calculator. Keep your phones and other devices silenced and
stored away from your desk.
OFFICE HOURS
Monday 1:30-3:00
Tuesday and Thursday 3:00-4:00
(1) If times other than the above are needed, please contact me to request an alternate
time.
(2) On campus students - please do not ask technical questions by email. Come see me in
my office hours such that we may discuss your question.
EOL students: Phone calls during the above times, or other arranged times possible.

There are many resources available online through the library – I suggest Compendex. Many
articles will be available in electronic format through the library. Some journals include:
Earthquake Engineering and Structural Dynamics; Soil Dynamics and Earthquake
Engineering; All of the ASCE Journals; Physics of the Earth and Planetary Interiors;
Earthquake Spectra; Journal of Earthquake Engineering; Seismological Research Letters;
Bulletin of Seismological Society of America; Bulletin of the New Zealand Society for
Earthquake Engineering, Journal of the American Concrete Institute.
Journal reviews are limited to 2 pages, 1.5 spacing. Text summaries are limited to 1 page, 1.5
spacing. In each case, this is not just a summary, but also a discussion in your own words
about what you learned, how it relates to course content, and any questions you would like
raise.

CAPTURED LECTURES
This on campus course will be captured and distributed via the Internet and/or electronic
media as part of the Engineering Online (EOL) program for the distance students. These
video recordings may contain an image of you entering the classroom, asking a questions or
being a part of the studio class. Please notify Dr. Linda Krute, Director of EOL, in writing at
ldkrute@ncsu.edu if you DO NOT want your image to be included in the lecture presentation.
If we do not hear from you after the first week of the class, we will assume that you are in
agreement with this procedure.
ATTENDANCE POLICY
Attendance is mandatory, unless prior arrangements are made, or due to illness or other
emergencies. Students are responsible for all material presented in class. See
http://policies.ncsu.edu/regulation/reg-02-20-03. This is an EOL course, and all students will
be given access to all online materials, including video lectures. On-campus students must
still attend class, with the exceptions noted above.
ACADEMIC INTEGRITY STATEMENT
Students will adhere to the academic policy set forth by University Code of Student Conduct
(http://policies.ncsu.edu/policy/pol-11-35-01) Plagiarism and cheating are attacks on the very
foundation of academic life, and cannot be tolerated within universities. Section eight (8) of
the Code defines academic dishonesty and provides information on potential sanctions for
violators of academic integrity. You will be asked to sign the following statement on each
test and on the final: “I have neither given nor received any unauthorized aid on this test.”
NCSU STATEMENT FOR STUDENTS WITH DISABILITIES:
Reasonable accommodations will be made for students with verifiable disabilities. In order to
take advantage of available accommodations, students must register with Disability Services
for Students at 1900 Student Health Center, Campus Box 7509, 515-7653.
http://www.ncsu.edu/provost/offices/affirm_action/dss/ For more information on NC State's
policy on working with students with disabilities, please see
