Goals:
This course introduces the basic topics of structural analysis. The goal is to
enable the students to solve elastic problems involving any external loading,
with particular focus on the calculation of stresses and deformations.
Lecture or lab
topics:
1. Review of static’s. Internal forces. (1 class)
2. Review of approaches to the solution of trusses (1 class)
3. The concepts of normal stress and shear stress (2 classes)
4. Stress-strain curves. Definition of normal strain (2 class)
4. Uniaxial, biaxial, triaxial states of stress. Definition of shearing stress.
Hooke’s Law for the general case. (2 classes)
5. Statically determinate and indeterminate structures subjected to axial forces.
Temperature effects. (3 classes)
6. Effects of torque on structures. Shearing stress and angle of twist (2 classes)
7. Statically determinate and indeterminate structures subjected to torque.
Interaction of gears (2 classes)
8. Transversally loaded beams. Internal shear and internal moment. Diagrams.
(2 class)
9. Normal stress due to bending moment (2 classes)
10. Shear stress due to shear (2 classes)
11. Relationship between external load, shear and moment. Internal force
diagrams (3 classes)
12. Design of beams for normal stress and shear stress (1 class)
13. Stress transformation. Analytical and graphical approach (Mohr’s circle)(2
classes).
14. Midterms and final exam. (2 classes)
Due to the mostly theoretical content of the course, and to the relatively simple
problems, the usage of computer programs is limited. General mathematic
programs can be used to solve simple differential equations or to calculate
solutions to elementary integrals or linear systems of equations.

Specific Examples of ABET Criteria 3
a: The assigned homework covers a wide range of problems associated with the theoretical topics analyzed in class, and
include problems for the solution of which a moderate level of engineering judgment is required. The solution of the
proposed problems requires extensive use of the mathematics and calculus background of the students, as well as
ingenuity and intuition.
c: The covered topics and the assigned homework explicitly involve the design and/or the verification of a simple
structural system or of an assembly of simple structural systems, including the design process necessary in order to obtain
a structure compatible with given deformability or stress constraints.
e: The very nature of the topics covered by the course requires the students to become able to identify, formulate and
solve the given structural problems.
Specific Examples of ABET Criteria 8
a: Basic knowledge of trigonometry, analytic geometry, linear algebra and calculus are necessary for the solution of the
vast majority of the problems assigned during the course, and the students need to apply all these theoretical topics on
practical problems.
d: The topics taught in this course will allow the students to be able to actively participate in the design process possibly
involved in the professional component of the curriculum.
