For nearly 30 years ETABS has been recognized as the industry standard
for Building Analysis and Design Software. Today, continuing in the same
tradition, ETABS has evolved into a completely Integrated Building Analysis
and Design Environment. The System built around a physical object based
graphical user interface, powered by targeted new special purpose algorithms
for analysis and design, with interfaces for drafting and manufacturing,
is redefining standards of integration, productivity and technical innovation.
The integrated model can include Moment Resisting Frames, Braced Frames,
Staggered Truss Systems, Frames with Reduced Beam Sections or Side Plates,
Rigid and Flexible Floors, Sloped Roofs, Ramps and Parking Structures,
Mezzanine Floors, Multiple Tower Buildings and Stepped Diaphragm Systems
with Complex Concrete, Composite or Steel Joist Floor Framing Systems.
Solutions to complex problems such as Panel Zone Deformations, Diaphragm
Shear Stresses, and Construction Sequence Loading are now at your fingertips.
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.
Here are some reasons why?:
 Object based graphical modeling with unique finite element formulations
and auto-meshing enable ETABS to accurately model floors and walls using
finite elements as an alternative to rigid diaphragms. This provides important
advantages: Accurate, automatic distribution of forces/ moments through
slabs and walls for design, and the ability to check and design for axial
force in beams - none of which is possible when using rigid diaphragms.
No more error prone assumptions regarding uniform load distribution through
floors, walls, and framing. Automatic calculation of floor and wall self-weight,
mass and stiffness based on section properties.
Auto-meshing provides automatic transfer of gravity and lateral floor
and wall loads, even with openings, overhangs, or variable thickness One
integrated system - no more time consuming error prone transfer of results
and models between different modules or programs for gravity and lateral
load analysis and design. Concrete, composite beam, joists, steel design,
drift all in one package.
Shear walls - ETABS integrates stresses into one area based on user specified
pier or spandrel label. For example, if 8 wall finite elements have been
assigned the same pier label, forces and moments will be integrated such
that all 8 elements are treated as one (1) pier/column for reinforcement
design, and in reporting of shears and moments. Among other advantages,
this enables ETABS to treat multiple wall panels as one 3D section if
desired. Torsion is automatically converted into shear. Uniform rebar
or user pattern. Easily assign openings, variable thickness.
 Composite beam design (link to Ashraf's paper on composite beam)- options
for camber, vibration, partial composite connection, user defined or uniform
shear connector layout, cover plates, pattern loading, shored or unshored
design.
Steel member sizes can be optimized based on strength per design code
and/or drift requirements with user defined auto select lists of sections.
Compare ETABS optimization to manual trial and error, analyzing one section
per member at a time.
Line constraint automatically 'connects' course mesh with finer mesh
for accurate transfer of loads - this is often the case when walls come
into floor elements or into beams where common joints are not shared.
Big time saver that prevents errors in load transfer between objects.
Only ETABS offers this capability.
True physical member length - When designing and analyzing continuous
members which are intersected by other members, ETABS does not break up
the continuous member into multiple segments for reporting of results
or editing. Compare this with having to manage multiple segments and multiple
moment diagrams which represent just one continuous member.
For slab and foundation reinforcement design and punching shear checks,
ETABS will automatically transfer forces/moments on slabs for each load
case, slab properties and geometry into SAFE design software.
 Similar stories feature - When drawing or editing the model on one story,
changes and additions can automatically ripple down to similar stories.
ETABS provides output options you can really use - Instead of typical
output reports with non descript nodal deflections, forces & moments,
etc., ETABS organizes results to provide: interstory drift, center of
mass and rigidity of each level, story by story report of shears and overturning
moments, column and beam reactions reported separately on a story by story
basis. Results can be reviewed interactively by clicking on members/joints,
printed reports, export to Excel or Access database, and generation of
usable DXF drawings and CIS/2 files.
Automatic generation of lateral loads - 9 built-in U.S. and international
design codes for auto wind loading with windward and leeward assignment
options. 7 codes for auto earthquake. Steel design options based on lateral
drift.
Automated code design beyond the basics - Automatic load combinations
per design code, automatic determination of unsupported lengths, much
more.
Advanced analysis - Nonlinear pushover analysis using large deflection
with plastic hinge stress/strain curves. Nonlinear staged construction
analysis, base isolators, gaps/hooks, structural pounding analysis, linear
and nonlinear dampers, P-Delta analysis, rigid link constraints to connect
meshes which do not share common joints, panel zone springs at beam/column
intersections including effects of doubler plates. Response spectrum,
linear and nonlinear time history dynamic analysis, consideration of vertical
motion components as well as lateral.
