I have created a model using shell elements to model a concrete structure. I am having difficulty checking or understanding the output provided by RAM Elements for a shell. The outputs are "Internal Forces in Shells", "Shells - Nodal Forces", and "Shells - Face Forces". If I want to check my concrete member for shear, which shear value should I use? I notice the program uses the "Internal Forces in Shells" value to design the moment reinforcing so I assume the shear value for the concrete should also come from this category. The output is on a per foot basis for "Internal Forces in Shells", how is this converted to a shear value to compare to a shear strength calculated from ACI?
Thank you in advance for helping me understand the output and how to use the information properly.
