Geotechnical Earthquake Engineering

By Prof. Kousik Deb | IIT Kharagpur

Learners enrolled: 546 | Exam registration: 51

ABOUT THE COURSE:

The course will focus on the design of geotechnical structures under earthquake condition. The determination of the soil properties by field and laboratory tests for seismic design of geotechnical structures will also be discussed. Soil liquefaction and soil improvement techniques for remediation of seismic hazards like liquefaction will be discussed. In the undergraduate core courses, these topics are either not covered or discussed in simplified form. In the proposed course, these topics will be discussed in detail. This course is useful for both UG and PG student. Field Engineers can be benefited from this course as the design of geotechnical structures under seismic condition (those are not generally covered in UG core foundation engineering course) will be discussed here.

INTENDED AUDIENCE: UG and PG students. Research Scholars and Practicing Engineers can also take this course.

PREREQUISITES: BE Students can take after completing third year or after completing "Soil Mechanics" and "Foundation Engineering" courses. ME and PhD students can take during first year of their course work.

INDUSTRY SUPPORT: Most of the Civil Engineering companies

The online registration form has to be filled and the certification exam fee needs to be paid. More details will be made available when the exam registration form is published. If there are any changes, it will be mentioned then.

Please check the form for more details on the cities where the exams will be held, the conditions you agree to when you fill the form etc.

CRITERIA TO GET A CERTIFICATE

Average assignment score = 25% of average of best 8 assignments out of the total 12 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100

Final score = Average assignment score + Exam score

YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.

Certificate will have your name, photograph and the score in the final exam with the breakup.It will have the logos of NPTEL and IIT Kharagpur .It will be e-verifiable at nptel.ac.in/noc.

Only the e-certificate will be made available. Hard copies will not be dispatched.

Once again, thanks for your interest in our online courses and certification. Happy learning.
