ETABS

ETABS is an integrated software package for the structural analysis and design of buildings. ETABS offers unmatched 3D object based modeling and visualization tools, fast linear and nonlinear analytical power, sophisticated and comprehensive design capabilities for a wide-range of materials and design codes (Eurocode, US and other international codes).

ETABS has powerful post processing features with graphic displays, reports, and schematic drawings that allow the engineer to quickly and easily decipher and understand analysis and design results. The state-of-the-art SAPFire 64-bit solver allows extremely large and complex models to be rapidly analyzed. ETABS supports nonlinear modeling techniques such as construction sequencing and time effects (e.g., creep and shrinkage).
 
Design of steel and concrete frames (with automated optimization), composite beams, composite columns, steel joists and concrete and masonry shear walls is included. ETABS provides an unequaled suite of tools for structural engineers designing buildings, whether they are working on one-story industrial structures or the tallest commercial high-rises.
