SF4204 Shallow Foundations Syllabus:
SF4204 Shallow Foundations Syllabus – Anna University PG Syllabus Regulation 2021
OBJECTIVES:
To impart knowledge to select, analyse, geotechnical and structural design of shallow foundation depending on ground conditions.
UNIT I FOUNDATION DESIGN DECISIONS
Types of foundation – Types of Shallow foundation, their applicability – Selection of type of foundation – conceptual design principles – General and additional considerations – Depth of foundations – IS codal provisions.
UNIT II BEARING CAPACITY
Theories of bearing capacity – Ultimate and Safe Bearing capacities in Homogeneous – Layered soilsand Rocks – Evaluation of bearing capacity from in-situ tests– Bearing capacity of foundations in slopes – Bearing capacity under eccentric loading – partial safety factor approach – Codal provisions.
UNIT III SETTLEMENT AND ALLOWABLE BEARING PRESSURE
Component of settlement – Influence of foundation stiffness approach to settlement computations – immediate, primary and secondary consolidation settlement – stress path method of settlement evaluation – layered soil. Evaluation from in-situ tests – Allowable settlement – Allowable bearing pressure – codal provisions.
UNIT IV INTERACTIVE ANALYSIS AND DESIGN OF FOUNDATIONS
Analysis of foundation – isolated – strip – combined footings – Flat raft – Stiffened raft foundations. Conventional – elastic approach – Soil Structure Interaction Principles – Elastic half space approach – Winkler foundation – Structural design of Shallow foundation – Codal provisions.
UNIT V FOUNDATION FOR SPECIAL CONDITIONS
Foundation design in relation to ground movements – Foundation on compressible fills, expansive soils – Foundation for tower – special considerations for foundation for seismic zones and offshore environment. – Codal Provisions.
OUTCOMES:
On completion of the course, the student is expected to be able to
CO1 Differentiate various type of shallow foundations, their selection, design principles for different ground conditions
CO2 Apply appropriate bearing capacity theory and factors for different type of loading and ground conditions
CO3 Decide the design bearing pressure based on settlement, mode of loading and ground conditions
CO4 Perform interactive analysis for different types of shallow foundation and ground conditions
CO5 Perform analysis for different types of special foundation and special ground conditions
