Influence line using slope deflection.

[Suki]

I m trying to calculate the reaction influence line for a simple indeterminate beam problem.

I built up functions for fixed end moment and slope deflection equations. Now I m trying to calculate rotations at the end supports of the beam, I m getting error because the slope deflections equations are conditional expressions. I m expecting set of end moments when the load is placed on the particular element. How can I achieve this ?

Update: I was able to solve the system of equations symbolically but now the result do not match.

For example it does not match the boundary conditions.

I m sorry I could understand what you are trying to do ?

Have put a little more explanation in the file and included references where slope deflection equations come from.

Have added units. Metric system is used
