#CALCULATE MOMENT OF INERTIA T BEAM FREE#

Typically, when performing a static analysis of a load bearing structure, the internal forces and moments, as well as the deflections must be calculated. The fixed beam is an indeterminate (or redundant) structure. Redundant structures can tolerate one or more local failures before they become mechanisms.

To the contrary, a structure that features more supports than required to restrict its free movements is called redundant or indeterminate structure. If a local failure occurs to these, they would collapse. The structures that offer no redundancy, are called critical or determinant structures.

In this situation the structure could move without restriction in one or more directions. To the contrary, a structure without redundancy, would turn to a mechanism, if any of its supports were removed. In other words the fixed beam offers redundancy in terms of supports. Indeed the second fixed support could be removed entirely, turning the structure to a cantilever beam, which is still a sound load bearing structure. The fixed beam features more supports than required to be statically sound. The fixed beam features two fixed supports, one at each end Restraining rotations results in zero slope at the two ends, as illustrated in the following figure. Fixed supports inhibit all movement, including vertical or horizontal displacements as well as rotations. It features only two supports, both of them fixed ones. The fixed beam (also called clamped beam) is one of the most simple structures.
