Computer analysis is used to solve a series of complex mathematical equations that describe the behavior of the structure being analyzed.

The behavior of the entire structure is too complicated to describe mathematically, so it is divided into smaller segments that have well defined behavior.

Each of these segments influences the response of other segments in the structure. The response of the entire structure is determined by combining the responses of each segment.

The way that each segment behaves and how they interact is developed from physical laws, such as Hooke's Law, and material data obtained from tests.

Validation of computer analysis is done by comparing the results for complex structures to test results in a process known as benchmarking.
