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
