Instructor Lauren K. Stewart, PhD, PE School of Civil & Environmental Engineering lauren.stewart@ce.gatech.edu Office Hours: TBD, Mason 3141A Course Description This course introduces key concepts in structural engineering: the science, art and skill of designing various types of structures such that their behavior is as intended in a safe manner throughout their lifetime. Through case studies of structures and failures, demonstrations and lectures, students will understand how structures of all types (i.e. buildings, bridges, domes, dams, etc.) take and transfer loads, compute the effects of the loads on the structural members and determine the material and size of these members such that they are safe. Course Objectives During this course, the student will learn by actively participating in lectures and demonstrations, by solving individual homework assignments and completing an engineering project as a member of a small team. After the student completes the course they will be able to: Determine the behavior of structural systems as defined by gravity, lateral, thermal and other loads Represent three-dimensional structural systems as two-dimensional analysis models Compute the demand loads on members Design basic structural members made of commonly used materials Explain the force transfer mechanisms of the structure Prerequisites This course is intended as a technical elective for all levels of undergraduate students who have taken Statics: COE 2001 and have taken or are concurrently enrolled in COE 3001: Deformable Bodies. Course Conduct The Georgia Tech Honor Code is the standard of conduct for this course. The Honor Code is available at http://www.honor.gatech.edu/. Fall 2014 1
Website The website for the course is. Students are expected to check regularly for announcements and are responsible for the material posted. Modules The course is divided into six modules and will consist of lectures, demonstrations and laboratories. One individual homework and one group laboratory is included each module. The modules for the course are: 1. Structural Systems, Loads and Load Paths 2. Internal Forces and Behavior 3. Design 4. Building Materials and Construction 5. Hazards and Extreme Loads 6. Typical Civil Structures Homework Assignment of homework problems related to the lecture material will be made for each of the six modules and posted on T-square. Please be concise and neat in submitting solutions. All students must turn in their own homework assignments. Discussion of the homework problems with other class members is allowed, copying is not. Homework will be checked for excessive similarities and will be given a zero for the assignment. Assignments are due at the beginning of the class, late homework is accepted at a 25% markdown per day late up to three days. Late homework due to medical reasons will be considered with a doctor s note. Extensions for religious reasons or medical issues should be requested as soon as possible, prior to the homework being due. In-Class Laboratories Demonstrations/laboratories will be conducted during class time in small groups for each module. The groups will be assigned at the beginning of the semester. Each laboratory will have a short assignment which will be due no sooner than one week after the demonstration. Each group will turn in one writeup and each member will receive the same grade. Students are expected to attend all in-class laboratories. Make-ups will only be granted in exceptional circumstances and must be requested prior to the day of the demonstration. Attendance may be taken during these classes to ensure fair participation of all members of the group. Fall 2014 2
Exams There will be two one-hour exams in approximately the 8th and 14th week of classes covering the first three and the last three modules, respectively. These tests will be closed book and closed notes. Reviews will be conducted the class period immediately before the exam. Cheating off of another persons exam is unethical and unacceptable. Examples of cheating include, but are not limited to, bringing unauthorized material to exam, collaborating or sharing notes, talking during exam and using cellphones. Prior to the exam, all personal belongings will be placed in the front of the classroom. Please do not bring anything into the exam room which you are not comfortable leaving at the front. Cheating off of anyone elses work is a direct violation of the GT Academic Honor Code, and will be dealt with accordingly. Final Project Laboratory groups will build a model structure which will be analyzed and designed based on a performance index using cost, deflection and aesthetics given various loading scenarios. The structures will be tested on the Saturday after the 14th week of classes. Please put this on your calendar now and inform me immediately if there are any issues with this date. Student groups will prepare a technical document discussing their design concept, analysis, testing and forensic investigation. During finals week, each group will do a 15 minute oral presentation discussing their concept and findings. Every group member is expected to speak during the presentation. Textbook There is no official textbook for the course. Course notes, homework solutions and additional course material will be available to print on T-square. References for the course include: C.
