Abstrakty
The sensitivity of thin-walled bars with bisymetric open cross-section under static loading bas been investigated. The considerations are based on the classical assumptions of the thin-walled beam theory. The first and second variation of the static response of the bar due to a variation of the design parameters are derived. For finite-dimensional structural systems the second variation of the structure performance is derived. The mixed method is used. In the numerical examples dealing with the I-beam the first and the second variations of the internal force and displacement of the beam are calculated. The graph of the function, describing the influence of the variation of the design parameter along the beam on the structure response, is found. The linear and quadratic approximations of the exact relation between the structural performance change due to design variation is found and the approximation error is discussed.
