Moment and shear effects of shell elements

Moment and shear effects of shell elements

Moment and shear effects of shell elements

Hi all,

I have designed bridge deck using shell elements in CSIBridge. Since the solver and method of calculation is similar to other CSI products, I'm posting here. (Similar concrete bridges as shown in Watch and Learn videos for CSiBridge)

After running vehicular loading, I need to find the load effects due to the applied load, such as moment and shear. For shell elements, the result of stress and force can be displayed nicely. Thought, which one is the moment (M11,M22...) and correct shear (V12,V23,,,)?

I am fully aware of local axis direction, sign convention and other things, yet I cannot figure out which one represent moment and shear of let's say deck slab.


shed some lights on this matter pls
