Every part of a building project is subject to the effects of outside forces like earthquakes, sandstorms, weather changes, wind, to name a few. This is why Structural Engineers have to be proactive and extra vigilant when designing and constructing a structure.
Nowadays, most (if not all), structural engineers use 3D integrated structural analysis and design software to model geometries of structures that help them analyze loads much more efficiently. This helps them decrease the extra effort required for finite element analysis, eliminate errors caused by hand calculations, etc.
As analysis and design is such an integral part of a construction lifecycle, there are many software that claims they are THE ultimate answer for your requirements. Many of them say they have diverse features, such as analyzing diversified profiles of structural elements like slabs, foundations, walls, openings, beams, columns, bracings, etc., and that they can model structures of any material, check for geometrical errors etc., but not all of them stick to their promises.
We are not here to investigate which software is actually true to their words, instead, we are here to determine the important steps (or aspects), to consider before investing in an A&D software that can fulfill all your requirements.
