CONDUCT OF COURSE

 

1.         Structural Steel Design is a very practical activity. The course is designed to give the student a "can-do" capability and some confidence (although not overconfidence!) in his/her capability to design steel structures.  To help gain a feeling for the design process and for the behavior of steel structures, we will work together to design several steel structures, yet to be determined.  We will develop structural plans (using the analysis program SAP2000 for analysis support) for the structures.  We will also, if possible, go on a field trip to observe a structural steel building during erection.  The class will also study steel design in the more traditional classroom setting, with lectures that follow textbook, homework assignments, and exams over the material covered.  Many of the homework assignments will have a strong design component to them.

 

2.         All homework must be turned in as part of successful completion of the course. Problem solutions must be on standard engineering computational paper and must include the unambiguous problem statements and sketches of the problem.  For full credit, homework must be turned in by the end of the period for which the assignment is due. Only partial credit will be received for late homework, and it may not be graded.  Professional behavior and professional worked is required. 

 

3.         Attendance at all sessions (or pre-arranged excused absences) is required for successful completion of the course.

 

4.         The final grade will be determined from the results of the homework, hour examinations, final exam, and a semester project using the following weights:

 

Homework                                                                    30%

Midterm Exams                                                                           20%

Final Exam                                                                    20%

Semester Project                                                           20%

Classroom Participation                                                10%

 

Note: The CE524 students will be expected to do a more comprehensive semester project than the CE424 students. More details will be provided.
