Stresses versus steel verification The image below shows the tensile stress and the steel verification for 3 different beams: For Beam 1: based on...
How to do the elastic analysis for steel The elastic analysis can be done according to a 1st or 2nd order calculation. What is the difference between a...
How does the choice ‘1st or 2nd order calculation’ affect the buckling lengths There are 3 methods to calculate the buckling lengths: Non-displaceabable nodes (syn.: non-sway buckling lengths) Semi-displaceabable nodes Displaceabable nodes (syn.: sway...
What is the difference between local and global imperfections? Global imperfections (also called Δ – effect) are a (global) displacement of action line (of normal force) due to rotation...
How do I determine if the structure is sway or non-sway? To determine if a structure is sway or non-sway, you can calculate the global buckling factor . Click on .Choose...
