COURSE GOALS:

·        To introduce classical and some modern methods for analyzing determinate/indeterminate beam, truss, and frame type structures.

·        To provide the necessary background for the proper use of computer programs for structural analysis.

·        To provide understanding of the application of theoretical concepts to practical problems in bridge and building analysis.

 

SUMMARY OF COURSE OBJECTIVES:

At the conclusion of the course the student will be able to:

·        Construct shear and moment diagrams for determinate/indeterminate beam and frame type structures.

·        Determine axial forces in determinate/indeterminate truss type structures.

·        Determine deformations (deflections and rotations) of determinate/indeterminate structures using various classical and modern methods of analysis.

·        Construct influence lines for determinate/indeterminate structures and subsequently position dead and live loads to cause the maximum forces.

·        Apply theoretical concepts to practical problems in structural engineering.

·        Analyze different types of determinate/indeterminate structures using a structural analysis computer program and interpret the results.

·        Understand concepts of stiffness and energy as it relates to structural mechanics.

 

 

 

CONTRIBUTION OF COURSE TO MEETING THE PROFESSIONAL COMPONENT:

This course provides the student with the necessary background to perform entry-level professional work in structural analysis and civil (structural) engineering.

 

RELATIONSHIP OF COURSE TO PROGRAM OBJECTIVES:

This course satisfies the structural mechanics and analysis components of the CE program.

 

HOMEWORK, EXAMS, AND GRADING:

The final grade for the course will be evaluated based on the breakdown given below.

 

            3 In-Class Exams                                                                              54% (18% each)

            Final Exam                                                                                         25%

            Quizzes                                                                                              5%

            Homework (includes computer and laboratory projects)  16%

 

There will be 3 in-class exams and a final exam (comprehensive).  The in-class exams and final exam will cover material from class lectures, homework, and reading assignments.  All exams must be taken at the scheduled time and date set by the instructor unless prior arrangements are made.

 

Homework must be submitted on standard engineering paper in a professional format (i.e., neat and well organized) at the beginning of the class period on the assigned due date.  An overall homework average of 60% is required to pass the course.  Assignments will be graded based on both presentation and content.  Illegible and unorganized work will not be graded.  Ten percent of credit will be deducted for every day an assignment is late.  Homework turned in 3 or more days after the due date will receive no credit.  Make-up work will be considered on a case-by-case basis.

 

GENERAL POLICIES:

It is to the student’s benefit that he/she attends all class lectures since homework is assigned and unannounced quizzes may be given.  Unexcused class absences and academic misconduct will be dealt with according to the regulations specified in the 1999-2000 NMSU Undergraduate Catalog.

 

STUDENTS WITH DISABILITIES:

If you have or believe you have a disability, you may wish to self-identify.  You can do so by providing documentation to the Services for Students with Disabilities, SSD, located at Garcia Annex (Phone: 646-6840).  Appropriate accommodations may then be provided for you.

 

If you have a condition which may affect your ability to exit safely from the premises in an emergency or which may cause an emergency during class, you are encouraged to discuss this in confidence with the instructor and/or the director of SSD.  If you have general questions about the Americans with Disabilities Act (ADA), call the ADA coordinator at 646-3333.
