## Abstract This paper deals with static reanalysis of a structure with added degrees of freedom where the nodes of the original structure form a subset of the nodes of the modified structure. A preconditioned conjugateβgradient approach is developed. The preconditioner is constructed, and the impl
## Abstract This paper presents a universal method, iterative combined approximation (iterative CA) approach, for structural static reanalysis of all types of topological modifications. The proposed procedure is basically an approximate twoβstep method. First, the newly added degrees of freedom (DO
