STAAD Advanced Analysis is a module of STAAD.Pro that provides enhanced performance during analysis and a number of additional analysis features.

The Advanced Analysis Module provides STAAD.Pro with the following additional major features:

1. Faster solver for matrix inversion (reduced analysis time in large models and for those models requiring iterative solution)
2. Memory efficient eigensolution method like Arnoldi/Lanczos for solving large scale eigen problems
3. Load dependent Ritz Vector for efficiently extracting relevant modes for fast and accurate calculation of structural responses. This is particularly useful for large models where huge number of modes has to be extracted to get adequate mass participation.
4. Geometric Non-linear Analysis

1. Pushover Analysis
2. Steady State Analysis
3. Buckling Analysis by eignesolution with ability to plot the buckling mode shapes 
4. Advanced Non Linear Cable Analysis

Within STAAD.pro SELECT series 6, the user must specifically request the use of the Advanced Analysis Plus Engine option on the start screen:

Otherwise, when attempting to run one of the Advanced Analysis options the following type of warning will appear:
