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, although allowable stress and empirical
design methods will also be discussed. 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.
PREREQUISITE KNOWLEDGE
Students should be very familiar with reinforced concrete design and structural analysis procedures.
Undergraduate students are required to have a 3.0 minimum GPa in structures and mechanics courses
(214, 313, 325, 327, 425, 426, 420) 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.

TA AND MESSAGE BOARD
The TA for the course is Steven Fulmer (sjfulmer@ncsu.edu). EOL students should use Steven as the first
point of contact. 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
