Hi everyone and thanks for your interest in this problem. I have a trouble calculating the vertical displacement of the midside of the Scordelis-Lo roof (check the following page for the roof schematic)

I believe it is a...
The picture is just a sample mesh. The real mesh is different of course and has 100's elements. My question is about the assembly. Do you see any thing wrong with that? is my analogy right?
the strain-displacement relations are for the shell theory ( defined with the radius of curvature and angle - Cylindrical coordinates). The elements will form square tube if they are defined with flat (plate) elements in cartesian coordinates.
Dear readers,
I will make the long story short, so consider the sample shell geometry shown: ( 3 x 4 elements - 4 nodes/element)
