Assalam o alaikum,
In Etabs, How to interperate Shell stresses/Forces. I highlighted M22 Force and i got max value as 2.61 in kip-ft units and minimum as -5.112 in Kip-ft units. What i found from the link
http://docs.csiamerica.com/help-files/etabs/Menus/Display/Show_Member_Force_and_Stress_Diagrams/Shell_Forces_Stresses_Form.htm
that
M22: Direct moment per unit length acting at the mid-surface of the element on the positive and negative 2 faces about the 1-axis.
Does it mean -5.112 Kip-ft/ft and is M22 the moment for which i am to calculate vertical steel. Kindly suggest me the value of Mu for which i am to design reinforcement. I have also attached Picture.
