But while Diamonds has 3 scenarios to calculate the buckling length, 1\u20222\u2022Build only contains one of the three: semi-displaceable nodes. <\/p>\n\n\n\n<p style=\"font-size:16px\">For each bar, 1\u20222\u2022Build therefore calculates the structure twice: once for buckling about the strong axis by applying a load perpendicular to the strong axis and once for buckling about the weak axis by applying a load perpendicular to the weak axis. In the second case \u2013 buckling about the weak axis \u2013 1\u20222\u2022Build naturally takes into account that the structure you have defined cannot move in a direction perpendicular to the XY plane at the ends of the bars.<\/p>\n\n\n\n<p style=\"font-size:16px\">To change the buckling lengths:<\/p>\n\n\n\n<ul>\n<li>For steel or timber cross-sections:\n<ul>\n<li>Click on the icon <img decoding=\"async\" class=\"wp-image-7478\" style=\"width: 30px;\" src=\"https:\/\/support.buildsoft.eu\/wp-content\/uploads\/2022\/04\/KnpoStabiliteit.png\" alt=\"\"> to show the results for the stability.<\/li>\n\n\n\n<li>Double click a bar to open the detailed results of the stability.
