CSI ETABS 23.1.1

Computers and Structures, Inc. (CSI) has released ETABS 23.1.1 (4293). This release introduce support for importing SAFE models at user-selected story levels, with enhanced options for merging geometry, property definitions, and load assignments. FEM-based buckling analysis of steel sections is now available via the integrated BucklingFEM plugin, enabling detailed eigenvalue buckling analysis of steel frame elements, capturing both global and local buckling modes. Shear wall design, concrete frame design, and reinforced concrete and PT slab design per ACI 318-25 are now supported. Additional new codes include shear wall design per CSA A23.3-24 and CSA A23.3-19, concrete shell design per Eurocode 2-2004, and concrete frame design per TCVN 5574:2018…………
