    General Information

    Prerequisites
    INCI 4022 - Structural Analysis II
    Textbooks
    • Robert E. Sennet , Matrix Analysis of Structures, Waveland Press, Inc., 2000
    Office hours
    • Tuesdays 1:30 PM - 3:00 PM.
    Course description
    Rigidity and flexibility concepts. Matrix transformation. Matrix method of rigidity and flexibility, substructure and introduction to finite elements.
    Primary objective of the course
    The purpose of this course is to expand the student knowledge of the stiffness and flexibility methods studied in the basic structural analysis courses. The students will be able to implement the method developing their own computer program to analyze structures. This is an advanced course for senior and graduate students interested in the area of structures. This course is a pre-requisite for INCI 6018 – Matrix Analysis of Structures II.

    Rules

    Exam attendance

    Only a valid reason can justify a student's absence to any of the exams. The student who has a problem for coming to any exam must contact the professor in advance to discuss his/her situation and work out a solution. In the event that an unforeseeable problem, like a sudden disease, should befall a student, he, or one of his friends or a family member should contact the professor as soon as possible but not more than three days after the exam's date to inform the professor of the problem. E-mail and Internet contacts are acceptable. A written evidence of the problem must be submitted as soon as possible. Failure to act according to these rules will result in a grade of "0" (zero) in the exam. Students are warned of the serious implications that an absence to any exam will have.

    In some rare instances, frivolous excuses may be considered by the professor. In those cases and if the professor decides to grant a make-up exam, such exam will be worth less than the 100% of the regular exam. The value of the exam will be left to the professor's discretionary decision. The student will lose any rights to complain against this determination.

    Homework

    One fifth of the final grade is obtained from assignments. Keep all your homework in a neatly organized folder or notebook and submit it with each new assignment. You will be graded according to the presentation, the clarity of your solving process, the correctness of your solution method, and the accuracy of your calculations.

    Assignments are expected to be individual work. Students are encouraged to consult one another or the professor regarding problems encountered in the process of working the assignment. However, the final work must reflect an individual work, without any shred of doubt. The professor will not tolerate any attempt to cheat, however minor it may be. An attempt to cheat will inevitably result in a zero (0) grade in that assignment for both the offender and the student who allows his/her work to be copied. The professor strongly believes that working on your own enhances your chances of passing the class.

    Internet registration

    All students must register in the class web page. The registration form can be found below. This will allow the professor to communicate faster with the students as a group or individually. Also, by registering you will be able to retrieve special assignments and look at your performance and individual record.

    Examination dates and grading

    Two partial and one final examinations will be offered throughout the semester. The exam dates and how final grade will be determined are shown below

    Exam Date Percentage
    First Partial September 18th, 2002 100 points
    Second Partial October 28th, 2002 100 points
    Final Exam December 10th, 2002 (9:45 AM) 100 points
    Homework ~ 100 points
    Computer project ~ 100 points
    Total ~ 500 points

    The curve for the final grade is

    Percentage P Grade
    P ≥ 90% A
    80% ≤ P < 90% B
    70% ≤ P < 80% C
    60% ≤ P < 70% D
    P < 60% F
