Fixed vs pinned support

WebFeb 25, 2024 · Fixed based require large footings - uneconomical in most instances; also, very difficult to get full fixity with a pad bases once the base rotates under moment. Only piled foundations with thick pile caps may offer anything close to full fixity! 3. WebWhen the FIXED or FIXED BUT type of support is specified, for those degrees of freedom which are to be treated as fully restrained, STAAD assumes the displacements to be known quantities whose value is zero. Hence, those degrees of freedom are not considered for the stiffness matrix, and their value is not calculated.

The first condition we would like to consider is a column with one fixed end and one free (unguided) end. By observation we see that this is identical to a pinned end column with a length of 2L.
