ETABS is the Acronym for EXTENDED 3D ANALYSIS OF BUILDING SYSTEMS, is a software developed by Computers and Structures, Inc. (CSI); a Berkeley, California-based engineering software company founded in 1975. ETABS is an engineering software product that can be used to analyze and design multi-story buildings using grid-like geometry, various methods of analysis and solution techniques, considering various load combinations.
ETABS can also handle the largest and most complex building models, including a wide range of nonlinear behaviors, making it the tool of choice for structural engineers in the building industry, yet it is easy to use. ETABS can be effectively used in the analysis and design of building structures which might consist of structural members like beams, columns, slabs, shear walls etc., With ETABS you can easily apply various construction materials to your structural members like concrete, structural steel, Reinforced Concrete etc. ETABS automatically generates the self-weights and the resultant gravity and lateral loads.
