EQE 590 - Soil Dynamics and Earthquake Response Analysis

COURSE NO AND TITLE : EQE 590 - Soil Dynamics and Earthquake Response Analysis

INSTRUCTOR : Assoc. Prof. Dr. S. Ümit DİKMEN
The aim of the course is introduce the principles of soil dynamics and its applications in earthquake response analysis of sites. In this respect, the course will start with a brief introduction of basic continuum mechanics, dynamic analysis and nature of seismic waves as applied in geomechanics. It will be followed by a detailed treatment of 1D and 3D wave propagation. Then both the theoretical and practical aspects of earthquake response analysis will be covered, including with some hands on experience with well-known and widely used software in the subject. The treatment of the subjects covering local site effects, liquefaction and soil structure analysis will be made in the last quarter of the course.
