7000+ certificate courses from Google, Microsoft, IBM, and many more.

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
