Hi Richard Ay,

Can you please clarify, why Caesar-II program calculate the deflection of a piping using the fixed end method instead of mean of simply supported and fixed end method.

CAESAR II implements a finite element solution. You can find a number of texts on this subject.

With your information, it seems that finite element solution calculates the deflection equal to the fixed end method.

I suppose Caesar uses a stiffness matrix formulation for elements, including an axial term of the stiffness matrix, a lateral and rotational stiffness term and- depending on options, adding stiffness terms as "Bourdon" effects, etc.

Under these circumstances, I don’t understand how can be done a clarification as you required. Maybe I'm wrong and I'm not able to understand deeply your question.

Best regards.
