FEM: Variable Section, 2 and 3 Spans Str.

FEM: Variable Section, 2 and 3 Spans Str.

Today I post 2 of the examples of the 2D frame FEM system I have built to solve problems in Mathcad.

Note in the deflections that the beams need to be bigger for proper behaviour; it is the analysis what I have implemented, not a design.

While doing it I have noticed that definition of aL and aR in the sheets is wrong in aR not being abscissa, but distance from right end.

You will avoid some future puzzle thinking by substituting the definition of aL and aR in the sheets by...

distances to respective quoted end of the segment in which the concrete head will be taken of constant width (affect only cases in which is not taken constant all over the length)
