SF4006 Dynamics of Soils and Foundations Syllabus:
SF4006 Dynamics of Soils and Foundations Syllabus – Anna University PG Syllabus Regulation 2021
OBJECTIVES:
To understand the basics of dynamics – dynamic behaviour of soils – effects of dynamic loads and the various design methods.
UNIT I 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 II DYNAMIC SOIL PROPERTIES AND BEHAVIOUR
Dynamic stress – strain characteristics – principles of measuring dynamic properties – Laboratory Techniques – Field tests – Factors affecting dynamic properties – Typical values- Dynamic bearing capacity – Dynamic earth pressure.
UNIT III FOUNDATIONS FOR RECIPROCATING MACHINES
Types of Machines and Foundations – General requirements – Modes of vibration of a rigid foundation, block method of analysis – Linear Elastic weightless spring method – Elastic half – space method – Analog models ; Design of Block foundation – Codal Provisions
UNIT IV FOUNDATION FOR IMPACT AND ROTARY MACHINES
Dynamic analysis of impact type machines – Design of Hammer foundations – use of vibrator Absorbers – design – Codal recommendation. Special consideration for Rotary machines – Design criteria – Loads on Turbo Generator Foundation – method of analysis – Design; Dynamic soil – structure – Interaction, Codal Provisions.
UNIT V INFLUENCE OF VIBRATION AND REMEDIATION
Mechanism of Liquefaction–Influencing factors -Evaluation of Liquefaction potential based on SPTForce Isolation – Motion Isolation – use of spring and damping materials – vibration control of existing machine foundation – screening of vibration – open trenches – Pile Barriers – salient construction aspects of machine Foundations.
