  • 2005 Catalog Data: CE 308-Analysis of determinate and indeterminate structural systems. Determination of forces and displacements. Classical analysis methods, influence lines, and introduction to matrix stiffness formulation.

  • Prerequisites: CE 302, pre-or-corequisite CE 314.

  • Meeting Times and Location: MWF 9:00-9:50am in Tapy 218

  • Required Textbook: Structural Analysis, Russell C. Hibbeler, Prentice Hall, 5th Ed, 2002.

  • Goals: This course is designed to provide students with the knowledge that most structural systems generally can be modeled with linear equations. Students with a good grasp of linear algebra, calculus, and physics will proceed rapidly with this new knowledge. Students will learn that the most important part of a structural analysis is the prescription of the external loads on the structure; this part requires considerable judgment, and students will begin their training in this area. Deflections and deformations of the structural system are functions of these external loads, and also of the boundary conditions and geometry of the system. Students will learn which equations must be employed to solve for the unknown forces and displacements in a structural analysis.

May 9 Final Exam (7:30am to 9:30am)


Conduct of the Course:
This course is a three-credit course that will meet three times per week. Hourly exams will be given at announced times. A portion of each lecture period following an exam will be devoted to a discussion of the exam solutions. Solutions to homeworks will be in the reserve section of the Centennial Library after the due date of the homework.

Homework generally will be assigned weekly and will be due one week later. The assignments will be graded and will be the basis for concepts tested in the exams. The homework's are mandatory, as are the exams. Make-up exams are not provided, but students who must travel can make arrangements to take the exams in advance of trips; the same is true for assignments.
