简介 PURPOSE : A re-analysis method of a structure for partly changing strength by adaptable substructure and a recording medium are provided to optimize design, to control displacement and stress and to analyze dynamic characters and behavior of the structure accurately by modeling the entire structure. CONSTITUTION : A structure is divided into a stiffness change portion and a stiffness fixing portion, and a residual degree of freedom is sorted(S110). A stress distribution coefficient matrix is calculated in the stiffness change portion per unit load according to degree of freedom in the structure(S120). The stiffness fixing portion is condensed to a substructure including residual degree of freedom by adaptable substructuring(S130), and equations of equilibrium on the residual degree of freedom on the initial structure and equivalent load vectors are calculated(S140). The equation of equilibrium is calculated by adding the changed stiffness matrix to the substructure stiffness matrix of the stiffness fixing portion, and the displacement of the residual degree of freedom is calculated(S150). Force of the stiffness change member is calculated by multiplying the stiffness matrix of the change member by the displacement vector(S160), and force of the stiffness fixing member is calculated(S170). © KIPO 2006
