Multidomain SFBEM and Its Application in Elastic Plane Problems
Publication: Journal of Engineering Mechanics
Volume 126, Issue 10
Abstract
In this paper, the multidomain spline fictitious boundary element method (SFBEM) is presented for analysis of elastic plane problems with different material constants or thicknesses throughout different domains. The problems are first reduced to nonsingular fictitious boundary integral equations with multidomain techniques being adopted. Then spline functions are adopted as trial functions to the unknown fictitious load functions in the deduced integral equations, and boundary-segment-least-squares techniques are used for eliminating the boundary residues. The proposed method is further applied in the analysis of high rise building structures, including framed shear walls, coupled shear walls, and frame-shear walls as well. Several typical numerical examples are given to show the accuracy and efficiency of the method.
