Abstract
A structure with decomposable stiffness matrix is hereafter called a regular structure. In addition to regular structures, there is another group of structures for which the stiffness matrix cannot be directly decomposed. These structures might be solvable (i.e., eigensolution or inversion) using the relationships in Chap. 2, through manipulation of either the stiffness matrix or the structure. However, such manipulations have to be compensated for, which might be computationally demanding. A structure that can be solved with minimum manipulations is hereafter called a near-regular structure. In general, there are two types of near-regular structures solution of which requires different algorithms and techniques. In this chapter near regular structures with additional members are discussed using displacement and force methods and methods are developed for the analysis and eigensolution of these structures.
