Application of consecutive method of the forward problem in identifying elastic restraint stiffness by frequencies of structure

Abstract

This paper presents the results of identification elastic restraint of the structure on the pipe - foundation. The model of the problem is the structure on the pipe - foundation as three-dimensional, linear elastic deformation, linked deposit - should be replaced with elastic restraint. The problem is solving by the consecutive forward problem of structure analysis and minimize the squared error between the measured and calculated natural frequencies of the actual structure and finite element model. From the numerical calculation shows, models, algorithms, and calculation programs are reliable. The program can be used to identify the elastic restraint of is the frame - pile structure as three-dimensional.
