ANALYSIS METHOD OF FOUNDATION STRUCTURE AND ANALYSIS SYSTEM FOR FOUNDATION STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide an analysis method of a foundation structure with which a transfer matrix between nodal points can be applied to a finite element method according to a displacement method.;SOLUTION: An analysis method of a foundation structure is provided with which the foundation structure constructed in contact with a ground is analyzed according to a finite element method. The analysis method then includes: a step S1 of using a beam model on an elastic bearing to create, as a fundamental equation, a relation of ground characteristics, an operational load, physical property of the foundation structure, a shape and a displacement amount; a step S2 of creating a relation between the fundamental equation and a deflection angle, a flexural moment and a shear force as a transfer matrix with the foundation structure as an element; a step S3 of performing deployment in which the turns of the flexural moment and the shear force in the transfer matrix are switched and the transfer matrix is converted into a rigidity matrix in a displacement method; and a step S7 of performing analysis from the rigidity matrix and a boundary condition according to the finite element method.;COPYRIGHT: (C)2013,JPO&INPIT
