SOIL-FRAMED STRUCTURE INTERACTION ANALYSIS- A NEW INTERFACE ELEMENT
Keywords:
INTERFACE ELEMENT, FRAMED STRUCTURE, INTERACTION ANALYSIS, FINITE ELEMENT METHODAbstract
INTERFACIAL BEHAVIOR BETWEEN SOIL AND SHALLOW FOUNDATION HAS BEEN FOUND SO INFLUENTIAL TO COMBINED SOIL-FOOTING PERFORMANCE AND REDISTRIBUTION OF FORCES IN THE SUPERSTRUCTURE. THIS STUDY INTRODUCES A NEW THIN-LAYER INTERFACE ELEMENT FORMULATED WITHIN THE CONTEXT OF FINITE ELEMENT METHOD TO IDEALIZE INTERFACIAL BEHAVIOR OF SOIL-FRAMED STRUCTURE INTERACTION WITH NEW COMBINATION OF DEGREES OF FREEDOM AT TOP AND BOTTOM SIDES OF THE INTERFACE ELEMENT COMPATIBLE WITH BOTH ISOPARAMETRIC BEAM AND QUADRILATERAL ELEMENT. THIS RESEARCH ALSO TENDS TO CONDUCT A PARAMETRIC STUDY ON RESPECTIVE PARAMETERS OF THE NEW JOINT ELEMENT. PRESENCE OF INTERFACE ELEMENT SHOWED CONSIDERABLE CHANGES IN THE PERFORMANCE OF THE FRAMED STRUCTURE UNDER QUASI-STATIC LOADING.
