Static analysis (non-variable loading)

This type of analysis is commonly used to model static loads that are permanently applied to the structure (e.g. self-weight, foundation settlement), normally leading to a pre-yield elastic response. If the applied load is such that the structure is forced into a slightly inelastic response, the program performs equilibrium iterations until convergence is reached.

In cases of relatively high nonlinearity, where the solution cannot be found with a single increment, the load is automatically subdivided into smaller steps and an incremental iterative solution is obtained by the program, with no need for user intervention. It is noted, however, that for such cases the use of static pushover analysis is recommended since it will provide the user with greater flexibility in running the analysis and interpreting the results.
