SF4004 Soil Structure Interaction Syllabus:
SF4004 Soil Structure Interaction Syllabus – Anna University PG Syllabus Regulation 2021
OBJECTIVES:
Focus is on idealization of soil response to closely represent continuum behavior and interaction analysis between the soil-structure with reference to relative stiffness of beams, slabs and piles under different loading conditions.
UNIT I SOIL RESPONSE MODELS OF INTERACTION ANALYSIS
Introduction to soil – Foundation interaction problems, Soil behavior, Foundation behavior, Interface behavior, soil-foundation interaction analysis, soil response models, Elastic continuum, Winkler, Two parameter elastic models, Elastic – plastic behavior, Time dependent behavior
UNIT II INFINITE AND FINITE BEAMS ON ELASTIC FOUNDATIONS
Infinite beam, General solution of the elastic line – concentrated and distributed loads on beams – Idealization of semi-infinite and finite beams. Classification of finite beams, different end conditions and loads – solutions – General method.
UNIT III PLATE ON ELASTIC MEDIUM
Infinite plate, elastic continuum, Winkler, Two parameters, Thin and thick plates, Analysis of finite plates, rectangular and circular plates, simple solution, ACI method, Analysis of highway and airfield pavements – solutions – General method.
UNIT IV ANALYSIS OF PILE AND PILE GROUPS
Elastic analysis of single pile – Solutions for settlement and load distribution – Simplified method for constructing load settlement curve to failure – Analysis of group settlement – Two pile interaction Analysis, Analysis of general groups – Theoretical solutions for free standing groups – Settlement of groups caused by compressible underlying strata – Use of design charts – Surface settlement around a group – Observed and predicted group behaviour.
UNIT V LATERALLY LOADED PILE
Load – deflection prediction for laterally loaded piles, subgrade reaction and elastic analysis, Analysis of pile group, pile raft system, solutions through influence charts.
