ETABS

In the last 30 years TABS and ETABS have set the international standards in structural analysis and design. They first took into consideration the characteristic properties of a building’s mathematical model, thereby allowing the graphical creation of a building’s model in the same sequence that the it will actually be constructed (slab by slab, floor by floor). Worldwide, ETABS is considered the most popular analysis and design software. The “Top Seismic Product of the 20th Century” (2006) and “Honor Αward in Engineering Software” (2002) awards, establish it as the innovator in structural analysis and design and the reference point for the entire market. 

The latest version of ETABS continues in that tradition, incorporating structural element terminology that is used on a daily basis (Columns, Beams, Bracings, Shear Walls etc.), contrary to the common civil engineering programs that use terms such as nodes, members etc. Additionally, it offers many automatic functions for the formation, analysis and design of the structural system in an efficient, fast and easy way. The user can easily create a model, apply any kind of load to it and then take advantage of the superior capabilities of ETABS to perform a state-of-the-art analysis and design.

ETABS is the solution, whether you are designing a simple 2D frame or performing a dynamic analysis of a complex high-rise that utilizes non-linear dampers for inter-story drift control. 

Areas of Application

• Analysis and design of building structures with a structural system consisting of beams, slabs, columns, shear walls and bracings. Different materials can be assigned to the structural elements within the same model such as steel, RC, composite or any other user-defined material
• Easy and automatic generation of gravity and lateral loads (seismic and wind loads) when compared with other FE general analysis programs

Advantages

• Graphic input and editing for easy and fast model generation
• 3D generation of the model through plan views and elevations
  Fast model generation using the concept of Similar stories
• Easy editing through the Move, Merge, Mirror and Copy commands
• Accuracy in dimensions by using Snaps (end, perpendicular, middle etc.)
• Fast object creation with one click of the mouse
• Multiple viewing windows.
• 3D view with zoom and pan capability
• 3D axonometric view of the model, plan view, elevation view, elevation development view, custom view defined by the user
• Graphic input of cross sections of any geometry and material (Section Designer)
• Copy and Paste of the geometry of a model to and from spreadsheets
• Export of the model geometry to .dxf files
• Integration with EC – Praxis 3J for the analysis and design of steel connections
• Integration with STEREOSTATIKA for easy import of model geometry and design of RC structures according to Greek Code
• Integration with eTools for the design of RC structures according to Greek Code, masonry structures according to Eurocode 6, RC jackets according to Greek Code and automatic creation of plastic hinges for pushover analysis
• Integration with SAP2000 for 3D analysis and design of structural elements including bridges, dams, tanks and buildings
• Integration with SAFE for the analysis and design of slabs of arbitrary geometry as well as mat foundations

Available versions

ETABS is available in two versions: PLUS and NONLINEAR. The former is ideal for all those who seek a complete package for the structural analysis and design of buildings while the latter is aimed at those who want to utilize the power of non linear analysis.
