Course Description (Proposed):
Structural Mechanics is a detailed introduction to the classical methods of analysis of both statically
determinate and indeterminate structures. Subject matter includes tracing of gravity and lateral loads in
building systems, the design and use of influence lines and deflection methods for beams and trusses.
The method of moment distribution is emphasized for continuous beams and frame analysis. Rigid
frame analysis with sidesway is also included.
Required Text
Structural Analysis, Hibbeler, Eighth Edition, 2012, Pearson Prentice Hall, ISBN: 978-0-13-257053-4
Learning Outcomes (Proposed):
Students completing this course will be able to:
1. Trace gravity loads in a building system.
2. Construct and use influence lines for beams and trusses.
3. Calculate deflection of beams and simple trusses.
4. Trace lateral loads in various bracing systems and perform approximate analysis on
indeterminate systems.
5. Analyze multi-span continuous beams and 1-story, 1-bay rigid frames.

Exams:
Seven closed book tests will be given. All equations/tables will be provided.
An excused absence from an announced test will need to be made up immediately.
Attendance:
Roll is taken regularly at the start of class. Attendance is used for borderline grades (i.e. 89.4 or 89.5)
Laboratories:
Lab periods are used for tests, lecture example problems, questions, and working on homework
problems.
Homework:
Homework problems will be assigned on a per topic basis. Answers are in the back of the textbook.
The tests will be comprised of similar problems. All work must be legible, done in pencil and
completed on 8.5” x 11” engineering paper in a "Given: Req'd: Sol'n:" format. These problems are to
be kept in a 3-ring binder and brought to the test. One or more problems will be collected as part of the
test grade.
Information:
Students with disabilities who believe that they may need accommodations in this class are encouraged
to contact the counselor working with disabilities at 678-915-7226 as soon as possible to better ensure
that such accommodations are implemented in a timely fashion.
Cheating of any kind will result in a grade of F for that exam and may result in a grade of F for the
course. Working together on lab report data /results is allowed; however, copying another student’s
work especially in the written sections is considered cheating and will not be tolerated. SPSU has an
Honor Code and a new procedure relating to when academic misconduct is alleged. All students should
be aware of them. Information about the Honor Code and the misconduct procedure may be found at
http://spsu.edu/honorcode/.
Honor Code
As a member of the Southern Polytechnic State University community of scholars, I understand that my actions
are not only a reflection on myself, but also a reflection on the University and the larger body of scholars of which it
is a part. Acting unethically, no matter how minor the offense, will be detrimental to my academic progress and
self-image. It will also adversely affect all students, faculty, staff, the reputation of this University, and the value of
the degrees it awards. Whether on campus or online, I understand that it is not only my personal responsibility, but
also a duty to the entire SPSU community that I act in a manner consistent with the highest level of academic
integrity. Therefore, I promise that as a member of the Southern Polytechnic State University community, I will not
participate in any form of academic misconduct. I also understand that it is my responsibility to hold others to these
same standards by addressing actions that deviate from the University-wide commitment to working, living, and
learning in an environment conducive to a quality education. Thus, I affirm and adopt this honor code of Southern
Polytechnic State University.
