@article{Machacek_Pichal_2018, title={Single-Crossarm Stainless Steel Stayed Columns}, volume={3}, url={https://ojs.imeti.org/index.php/AITI/article/view/803}, abstractNote={<p class="Abstract">Stability and strength of imperfect stayed columns are studied in 3D using ANSYS software. Following three tests of stayed columns with a reasonable geometry, the numerical modelling is validated and subsequently compared with available analytical and numerical 2D results. Arrangement and values of prestressing of ties and initial deflections of the columns affecting the nonlinear stability problem are discussed in a detail. The effect of nonlinear stress-strain relationship corresponding to common stainless steel material is shown, with respect to loading level corresponding to loss of the column stability. The assembly technique of the stayed columns is taken into account, comparing the method and stability/strengths of columns with fixed or sliding stays in the connection to the central crossarm. Finally some recommendations concerning the analysis and use of such stayed columns are given.</p>}, number={1}, journal={Advances in Technology Innovation}, author={Machacek, Josef and Pichal, Radek}, year={2018}, month={Jan.}, pages={9–16} }
