SAFE is described as 'is the ultimate tool for designing concrete floor and foundation systems. From framing layout all the way through to detail drawing production, SAFE integrates every aspect of the engineering design process in one easy and intuitive environment'. There are more than 25 alternatives to SAFE for Windows and Linux. The best alternative is Etabs. It's not free, so if you're looking for a free alternative, you could try Estru3D or sas-civil. Other great apps like SAFE are SAP2000 (Paid), SAFI 3D Structural Analysis (Paid), DYSSOLVE (Free, Open Source) and calc4fem (Free, Open Source).
For nearly 30 years, ETABS has been recognized as the industry standard for Building Analysis and Design Software. Today, continuing in the same tradition, ETABS has evolved into a completely integrated building analysis and design environment.
