Syllabus

Introduction [4 hours]
Background, Seismic Hazards, Mitigation of Seismic Hazards

Seismology and Earthquakes [6 hours]
Internal Structure of earth, Tectonic Plates, Plate boundaries, Fault, Elastic Rebound Theory, Other Sources of Seismic Activity, Location of Earthquake, Earthquake intensity, Earthquake Magnitude, Earthquake Energy

Wave Propagation [8 hours]
Waves in Unbounded Media, Waves in Semi Infinite Body, Waves in Layered Body, Attenuation of Stress Waves: Material Damping and Radiation damping

Soil Behaviour under Dynamic and Cyclic Loading [9 hours]
Elastic response of continua (1D and 3D), response of non-plastic and plastic soils under cyclic loading stress-strain models (elastic, visco-elastic, nonlinear elastic) Liquefaction

Dynamic Soil Properties and Foundation design[9 hours]
Stiffness, Damping, and Plasticity parameters of soils, Measurement: Field Tests and Laboratory Tests Correlations Assessment of liquefaction potential. Design of machine foundation using these dynamic properties.

The course provides a suitable background on the fundamentals of soil subjected to dynamic loads and provides a detailed background on seismology and earthquake engineering.

The course will provide the students an understanding of wave propagation through soils.

The course is designed to get an understanding on the behaviour of soil when it is subjected to dynamic loading like earthquake, loads from railways, runways, blasting, etc. which are very common in these modern days.

The course provides an understanding on the properties of soils which governs soil behavior under the dynamic loads.

The students are expected to understand the fundamentals of soil dynamics.

The students are expected to understand the fundamentals of seismology and earthquake engineering and explain the sources of dynamic load on the soils and foundations

The students are expected to understand the propagation of the wave in the soil system.

The students are expected to understand the vibration theory.

The students are expected to explain and interpret dynamic soil properties and their measurement by laboratory and in situ tests and determine the liquefaction susceptibility of a soil site
