EQE697 - Implementation and Understanding the Probabilistic Approaches in Earthquake Engineering

INSTRUCTOR : Prof. Dr. Sinan Akkar

COURSE OBJECTIVES : This course aims to introduce the major theory and concept behind the probabilistic approaches that are frequently used in earthquake engineering. The topics covered in the course are expected to help the student to better understand the recent modeling approaches in probabilistic risk and ground motion assessment.
 
COURSE CONTENT : 
  1. Major concepts in probability and discrete statistics (4 weeks)
  2. Monte Carlo simulation technique and its implementation (2 weeks)
  3. Ground motions as distributions: spatial and cross-correlations, risk targeted spectrum (3 weeks)
  4. Structural response as distributions: record-to-record variability, modeling of epistemic uncertainty (3 weeks)
 
PREREQUISITES : No specific prerequisite to take this course. However, students who have taken the math course in the Earthquake Engineering Department (or a similar one offered in the engineering departments of Bogazici University) will get familiar to the introductory topics faster. Students who have taken EQE 530 and EQE 520 will also have a quicker understanding of the topics given in items 3 and 4. 
 
DURATION & HOURS PER WEEK : 12 weeks, 3 hours per week
 
CONDUCT: 

Regular assignments every two to three weeks. Students are expected to make presentations in some assignments. Use of Matlab (or a similar software) would facilitate the solutions to the questions in the assignments. Exams can be either essay or oral type depending on the number of enrolled students. The weight of assignments is 60% and the weight of exams (one term and one final exam) is 40%.
