Course Objective:
Methods for the integrated design of components typically found in transportation structures including bridge super- and sub-structures, retaining walls , pavements, highway geometrics, traffic, drainage, etc. Usually offered in Fall semester beginning in 2008 and taught by practicing engineers.
Prerequisites:
CE 310 – Probability in Civil Engineering CE 323 – Hydraulic Engineering and Design CE 343 – Geotechnical Engineering and Design CE 363 – Transportation Engineering and Pavement Design
Co-requisite:
CE 335 - Structural Design in Concrete Text Books:
1. AASHTO (2007 or latest). AASHTO LRFD Bridge Design Specifications. (obtain from library or department). 2. FHWA NHI-06-088 (2006) Soils and Foundations Volumes I and II - downloadable free of charge at www.ncsconsultants.com – click link to "Downloads". 3. FHWA NHI-01-001 (2001).

Course Objectives:
1. Introduce students to concepts underlying the design of various components typically found in highway structures by using the Load and Resistance Factor Design (LRFD) methodology. 2. Emphasize quantification of uncertainties in design processes and importance of deformation-based design procedures. 3. Emphasize the importance of inter-disciplinary interaction for design of transportation structures. 4. Emphasize importance of considering construction procedures in design and vice versa 5. Introduce national standards produced by the Federal Highway Administration (FHWA) and American Association of State Highway and Transportation Officials (AASHTO). 6. Discuss brief case-histories using local projects with the objective of emphasizing concepts.
Topics Covered:
1 – Overview and Layout of Bridge Structures based on Traffic Projection, Roadway Geometrics 2 – Bridge Hydraulics 3 - LRFD, Loads and Load Combinations 4- Bridge Selection Process and Aesthetics 5– Methods for Bridge Superstructure Design 6 – Methods for Bridge Substructure Design 7 – Bridge Deck and Appurtenant Structures 8 – Constructability Evaluations, QA/QC, Plans, Specifications and Estimates 9 – Construction Management 10 – Course Summary, Introduction to Advanced Topics.
The attached schedule provides more detail on the weekly schedule of topics that will be covered and the responsible instructor. Contribution to professional component: (Units)
Math and basic science: 0 Engineering topics: 0 Design experience: 3
Class/laboratory schedule:
One 180-minute lecture per week including 30-minutes of break given at times and lengths at the lecturer’s discretion (e.g., 2 15-minute breaks, 3 10-minute breaks, etc.); weekly quizzes or homework, and a comprehensive final exam.
Relationship to program outcomes:
This course contributes to satisfying program goals 1, 2, 3, and 4 as defined by our faculty. The course also contributes to satisfying ABET outcome criteria 3A, 3C, 3E, 3K, 3L and 3M to the degrees indicated on the Course Classification Form.
Grading Policy:
There will be a quiz or homework assignment in the week following each lecture. You can take the quizzes online through the course website. Each quiz will be available from 8:00 am until 1:00 pm on Tuesday and from 6:00 pm until 11:00 pm on Wednesday.. Missed quizzes cannot be made up. Each quiz is worth 5 points towards your final grade. Occasionally, the instructors may select to supplement the quiz with a homework assignment. In that case, the homework and quiz will have a combined maximum score of 5 points.
CE 464A CE 564A Weekly quizzes or homework (14 @ 5 ea.) 70 70 Term paper --- 15 Final Exam 30 15 Mo, how much time will a student have to finish the quiz?? Presumably not the entire time that the quiz is available. How do we set this? I believe that we discussed the quiz availability time at one of the meetings before you came on-board. As I recall, Juan had asked Dr. Budhu how he keeps his students from sharing answers and Dr. Budhu suggested two different quizzes given at two different times. That is why I changed the paragraph above. Also, don’t we have to tell the students what the grading system will be? Cut-offs? Madified cut-offs, Statistical? Etc?
Term Paper: Graduate students enrolled in CE 564A are required to write a term paper on any subject related to LRFD as it applies to bridges. An extended abstract of the paper is due by Saturday October 11th and the full paper is due on or before Saturday December 6th. Late submittals will not be accepted. Lec.
