SABRE2 is a structural analysis and design software system focused on efficient, rigorous assessment of the strength of frames composed of web-tapered and general nonpris­matic steel I-section members.

In addition, SABRE2 can be used to assess compact/nonslender doubly-symmetric prismatic members. SABRE2 addresses all the AISC member strength limit states within its buckling calculations, and it can be used to model general lateral and/or torsional bracing as well as member continuity across braced points and any type of end restraints.
