The main purpose of the Section Builder is to calculate the various section properties of your section. The standard results refer to the results of a section when ignoring material property differences.

YouTubeでフォロー When you’ve finished building your section, simply click ‘Calculate’ on the top toolbar to determine the section properties. Note that the short wait time associated with each calculate is due to the Finite Element Analysis and Meshing that occurs in the background in order to solve for torsion constant, ねじり半径, and warping constant. FEA 法を使用してこれらの特性を計算することにより、, より高い精度が達成されます. Less robust programs only use approximate equations on the standard sections for these properties and fail to solve when a non standard section (下のクロスビームなど) 入力されます.
