### Column design and analysis

In a design situation, the expected load on a column would be known, along with the length required by the application. The designer would then specify the following:

1. The manner of attaching the ends to the structure that affects the end fixity.

2. The general shape of the column cross section (for example, round, square, rectangular, and hollow tube).

3. The material for the column.

4. The design factor, considering the application.

5. The final dimensions for the column.

It may be desirable to propose and analyze several different designs to approach an optimum for the application, so software such as this facilitates the process.

It is assumed that the designer for any given trial specifies items 1 through 4. For some simple shapes, such as the solid round or square section, the final dimensions are computed from the appropriate formula: the Euler formula, or the J. B. Johnson formula. If an algebraic solution is not possible, iteration can be done.
