GITAM University Design of Foundations for Dynamic Loading

 UNIT-I:
Elements of Soil Dynamics: Free and forced vibrations with and without damping for single
degree of freedom, natural frequency of foundation soil system – Barken, pressure bulb concept,
Pauw’s analogy.
UNIT-II:
Wave Propagation: Waves in elastic half space, Elements of seismic methods, steady state
vibrations.
UNIT-III:
Elastic Properties of Soil: Field and Laboratory methods, stress strain characteristics of soil under
dynamic loads, damping properties.
UNIT-IV:
Bearing capacity of soil : Under dynamic loads by pseudo static analysis and vibration Isolation.
UNIT-V:
Liquefaction: Mechanism, Laboratory methods, Evaluation of liquefaction in the field, factors
affecting liquefaction, Anti liquefaction measures, earthquake zones.
