Gen [ 結果查詢 ] Beam單元考慮7th DOF後，得到的Mb、Mt、Mw 結果是什麼意思？

請問，鋼構 Beam Diagrams 的扭力分析 Mb、Mt、Mw 是什麼意思？

#Bi-Moment#Twisting Moment#Warping Moment

Mb 是 Bi-Moment。Bi-moment in itself is not not measurable but it serves as convenient auxiliary in theory of warping torsion. It is moment in flanges times distance between flanges.
Mt 是 Twisting Moment。Twisting Moment (Mt) is St. Venant's torsion moment which generally refers to pure torsion moment.
Mw 是 Warping Moment。

請看 PDF 檔案。在那個檔案有 Mb、Mt、和 Mw 的說明。
