SF4007 Geotechnical Earthquake Engineering Syllabus – Anna University PG Syllabus Regulation 2021
OBJECTIVES:
To understand the dynamics of earth and its response, effect on earth structure and measures to mitigate the effects.
UNIT I ELEMENTS OF EARTHQUAKE SEISMOLOGY
Mechanism of Earthquakes – Causes of earthquake – Earthquake Fault sources – Elastic Rebound theory – Seismic wave in Earthquake shaking – Definition of earthquake terms – Locating an earthquake – Quantification of earthquakes.
UNIT II THEORY OF VIBRATION
Nature of dynamic loads – vibrations of single degree freedom system – free vibrations of spring – mass systems – forced vibrations – viscous damping, Transmissibility – Principles of vibration measuring instruments effect of Transient and Pulsating loads – vibrations of multi degree freedom system.
UNIT III GROUND MOTION CHARACTERISTICS
Strong Motion Records -characteristics of ground motion – Factors influencing ground motion – Estimation of frequency content parameters – Seismic site investigations – Evaluation of Dynamic soil properties.
UNIT IV DESIGN GROUND MOTION
Wave propagation Analysis – Site Amplification, Ground Response Analysis – Method of analysis – One Dimensional Analysis – Equivalent linear Analysis – shear beam Analysis – site effects – Design Ground Motion – Developing Design Ground Motion. Application of software package – codal recommendations.
UNIT V SEISMIC STABILITY ANALYSIS
Assessment of liquefaction potential based on SPT-N value – permanent settlement – displacement prediction – Mitigation of liquefaction induced damage – Microzonation for intensity – liquefaction – Bearing capacity analysis – Effects of Pile foundation – Response of slopes – Evaluation of slope stability – Pseudostatic – Newmark’s study of Block analysis – Dynamic analysis – Earth pressure due to ground shaking – Dynamic analysis.
