Instructor

and Office

Hours

Dr. Cem Akgüner (cem@tedu.edu, Room D312)

Instead of fixed/physical office hours, I have an “always may e-mail to

schedule or just drop-by” policy. At any time, you may come to my office

or send me a message with your questions/comments/concerns/re-

quests. I will try my best to talk to you in person or respond as soon as

possible within reason. Obviously, you may expect some delays outside

of regular working hours.

Textbook

1) Principles of Geotechnical Engineering – 10 th Edition, SI (2021) by B. M.

Das – Cengage Learning

You have access to the online resources through WebAssign (electronic

book, assignments, videos, etc.) for our textbook:

mechanics and civil engineering technology applied to natural and engineered/improved soils with their inherent and/or induced variability under multitude of conditions (time, loading, water flow) in order to build with the soil (e. embankments, road base layers, levees), upon the soil (e. bridges, buildings, roads) or within the soil (e. tunnels, basements, pipelines). Conducting labor- atory experiments to determine and critically evaluate soil properties is also an essential compo- nent of this course allowing for a hands-on experience.

Course Learning Outcomes

On successful completion of this course students will be able to: 1. Identify, set-up and perform appropriate laboratory experiments on soils under varying conditions in accordance with established standard procedures to determine their basic properties [B3] 2. Collect appropriate laboratory and in-situ soil data for civil engineering purposes, infer and appreciate their variability [B5] 3. Categorize soils according to standard methods, differentiate between their typical prop- erties and effects of water [B4] 4. Evaluate one- and two-dimensional water flow through/below soils and constructed facili- ties [B3] 5. Differentiate between total and effective stresses under changing loading and hydrau- lic/drainage conditions [B4] 6. Estimate the stress distribution and calculate short- and long-term settlements beneath loaded soil layers and their rate [B2] 7. Apply the fundamental principles mechanics of soils affecting soil properties and behavior leading to proper estimation of shear strength [B 3 ] 8. Distinguish the effects of dynamic loads and local soil conditions causing damages during earthquakes [B 2 ] 9. Improve written and oral communication skills through synthesis and presentation of tech- nical data [B4]

Relationship to Program Outcomes

This course contributes to fulfillment of the following program outcomes (4 count / 7 weights): PO2: Apply knowledge of mathematics, science, and engineering to design and implement original, innovative, and sustainable civil engineering systems, or processes to meet desired needs within a greater societal context. PO5: Design and conduct experiments; analyze and interpret data. PO6: Identify, formulate, and solve engineering problems. PO7: Demonstrate effective oral and written professional skills in English.

Course Assignments

A. Attendance, Lecture Notes, and In-Class/In-Zoom Activities ( 10 %): There will be multiple in- class/in-Zoom activities which will be graded. These may include but are not limited to activities

such demonstrations, discussions through Moodle forum, problem solving, question-and-an- swer sessions, minute-papers, competitions. Notes taken weekly during lectures will be given feedback and graded. Attendance will be taken and recorded through the attendance module of the TEDU LMS system. Failure to attend at least 70% of the lectures and recitations will lead to a grade of FX (Grading | TED Üniversitesi (tedu.edu). B. Homework and Quizzes ( 20 %): online homework and quizzes, homework (quizzes and problem sets) assigned through the WebAssign system You will conduct experiments, collect data, syn- thesize/contextualize the data, and write professional reports with all the appropriate/rele- vant content in accordance with the formatting that will be provided. Through experiments, you will gain a hands-on observational/innovative experience and an overall feel for various types of soils and their expected/typical/out-of-ordinary behavior. C. Exams I, and II ( 35 %): There will be two exams during the semester which I will try to give within class hours. Approximate dates are given on the weekly schedule. Exact times will be an- nounced later during the semester. D. Final ( 30 %): There will be a comprehensive final during the final exam weeks starting on June 12 , 2023 running through June 23 , 202 3. Exact date of the final will be announced by the uni- versity towards the end of the semester.
