Abstract: A new method for solving displacement sensitivity is presented in this paper. Based on the combined approximation, the first-order and the second-order sensitivities of the displacements are derived. The solution process is based on the single exact analysis results of an initial design and is suitable for different types of modifications of the design variables and structures.

Key words: displacement sensitivity, combined approximation, structural optimization, reanalysis method
