CE524 – ANALYSIS AND DESIGN OF MASONRY STRUCTURES
COURSE OBJECTIVE
To develop the techniques required for the design, analysis, and assessment of masonry structures. Particular
emphasis will be placed on limit-states design and strength design. Seismic design requirements will be
emphasized throughout the course – The IBC requires consideration of seismic issues in nearly every state.
Additionally, masonry structures are popular around the world and their use in regions of high seismicity is
extensive. If you can design a structure for seismic resistance, you will have the knowledge to tackle any
loading scenario as seismic design requires an understanding of the non-linear behavior of structural systems.
PREREQUISITE KNOWLEDGE
Students should be very familiar with reinforced concrete design and structural analysis procedures.
Undergraduate and non-degree seeking (PBS) students are required to have a 3.0 minimum GPA in
structures and mechanics courses (214, 313, 325, 327, 425, 426, 420 or equivalents) and are advised that this
is a graduate level class that on average will require at least 50% more effort than senior level undergraduate
courses.

LECTURES
Tuesday and Thursday: 10:15-11:30AM, Mann 406. The only electronic device to be used in class is your
calculator. Keep your phones and other devices off and in your backpack unless you use a tablet for
writing notes, if that is your preferred method.

TA AND MESSAGE BOARD
The TA for the course is Easa Khan (ekhan2@ncsu.edu). EOL students should use Easa as the first point of
contact for questions by email. Also, I encourage the use of the message board which will be monitored by
the TA to ask questions.

ADDITIONAL NOTES
1. All lectures, exams, and homework will be conducted in SI units.
2. I encourage discussions in class - don’t be shy! If you have a question or comment, it is likely others in
the class will have a similar thought. If your question is of the nature that it may take a long time to
adequately answer, I may ask you to come to office hours for a more detailed discussion.
3. For EOL Students: Any questions that are emailed to me that are relevant to the entire class will be
brought up for discussion at the following class period.
PAPER REVIEWS
Over the course of the semester, you will be required to read and review 5 technical journal articles. Topics
for each review are below, and each paper must come from refereed journal publications. Use the following
journals as a starting point - If you come across another journal, please see me before reviewing the article.
The Masonry Society Journal; ASCE Journal of Structural Engineering; ACI Structures Journal;
ACI Materials Journal; Earthquake Spectra; Earthquake Engineering and Structural Dynamics;
Journal of Earthquake Engineering; Engineering Structures
For each review, you should think of yourself as one of the ‘referees’. Discuss the technical aspect of the
paper. Do you agree with the findings? Do the findings contradict other researchers? Do not simply quote the
paper.
Each review is limited to 3 pages 12 point font 1.5 spacing, 1” margins all around. Include the abstract of
each paper with title and authors in each submission (on the first page), and start your review on Page 2. The
topics for each review must be as follows:
Review 1: Masonry materials (i.e. bricks, blocks, other unit types, grout, mortar)
Review 2: Historic preservation and/or retrofit
Review 3: Seismic behavior and/or retrofit
Review 4: Large scale structural testing of Masonry Structures
Review 5: Your choice of any Masonry topic
