Panel-zone definitions now include nonlinear behavior that is automatically generated based on ASCE criteria or specified as user-defined properties. The nonlinear behavior for panel zones allows the specification of a symmetrical multi-linear backbone curve with several available options for hysteretic behavior. Panel-zone acceptance criteria definitions have been expanded to allow the major and minor directions to be separately specified, and these can be automatically generated based on ASCE Drawings can be updated to reflect changes to the ETABS model and design results, while retaining drafting changes made to the drawings themselves.

Enhanced control is now available for the stiffness and damping of nonlinear link objects, including isolators, improving control of energy-dissipation behavior. Line and quadrilateral strain gauges can be defined, along with acceptance criteria, for measuring deformation, shear, and rotation Ultimate level. Results are now available on a step-by-step basis for load combinations of multi-step load cases, including plotted and tabulated results.
Absolute and relative displacements, velocities, and accelerations are now available for generalized displacements. AISC steel frame design added. IS concrete frame design updated for the IS seismic code. Design Parallel processing has been implemented for running design all types.
Added codes for creep, shrinkage, and stiffness aging: Eurocode , Australian Standard , New Zealand Standard and GL models. Creep and shrinkage behavior now includes the effect of rebar to reduce axial shortening of columns and walls. Modal damping option for linear and nonlinear direct-integration time-history analysis, providing more realistic and conservative results.
View response spectra for defined acceleration time-history functions. Response spectra can be requested either for a single time history function or a set of them. When viewing response spectra for a set of functions an option is available to view the envelope or the mean plus a multiple of the standard deviation.
Size of analysis results files reduced for multi-step nonlinear static and nonlinear direct-integration time-history load cases, typically affecting performance-based design models.
Integrated moment, shear, and torsion for design strips displayed onscreen and reported in tables. American, European, British, Canadian, along with several additional international codes are available. Punching-shear design checks in concrete slabs at columns and load locations specified by the user.
Overwrites for punching perimeters can be added as well as specifiying openings which affect the perimeter but are not explicity modeled. Apply thickness overwrites on a joint-by-joint basis, allowing slabs and walls to have nonuniform thicknesses. Joint offsets can also be applied. Pure event-to-event stepping solution implemented as an option for nonlinear direct-integration time-history load cases.
Define vibration analysis paths on floor slabs, along with parameters defining demand and capacity. Automated time-history analysis is performed for each case. Animated plot shows story accelerations, drifts, shears and overturning moments together on the same plot for time history and nonlinear static load cases. Performance-Based Design PBD is a major shift from traditional structural design concepts and represents the future of earthquake engineering.
These new procedures help assure that the design will reliably meet a desired level of performance during a given earthquake.
The fundamental component of PBD is nonlinear dynamic analysis where an attempt is made to capture the real behavior of the structure by explicitly modeling and evaluating post-yield ductility and energy dissipation when subjected to earthquake ground motions. ETABS introduces new special purpose options and algorithms for the practical and efficient application of these procedures.
ETABS is the most sophisticated and technologically-advanced software product available to structural engineers today. It defines the future of building design software, setting the stage for unsurpassed capability and efficiency worldwide. Built on a foundation of more than 40 years of research and innovation, ETABS sets the gold standard, yet again. Featuring versatile modeling technology, stunning graphics, efficient numerical methods and powerful optimization algorithms for design, ETABS offers unmatched levels of integration and productivity.
It addresses numerous international building codes while producing complete design reports and schematic construction drawings to meet the demanding needs of the modern structural engineering professional.

Structural Model. Learn More. Release Date: 11 Dec Performance-Based Design — Acceptance Criteria. Acceptance criteria can be assigned to Link and Panel Zone properties for use in performance checks. Acceptance criteria can be assigned to piers and spandrels that can measure forces, stresses, or stresses as a ratio of the square-root of the concrete compressive strength f'c.
Performance-Based Design — Results Display. A performance check can now include acceptance criteria from links, strain gauges, pier and spandrel forces, and panel zones, along with frame and wall hinges which were previously available. Multiple demand sets can be specified as well as multiple combination methods, allowing more control over the performance-check results.
Analysis can now run multiple load cases in parallel. This is particularly efficient for considering large suites of earthquakes in Performance-Based Design. Analysis errors, warnings, and informational messages are now stored and shown after the analysis completes, as well as accessible via database tables. Steel Frame Design. Russian steel frame design code to SP Concrete Frame Design. Concrete frame design per Russian code SP Structural Modeling.
A new material library for the Korean region has been added. The library contains steel, concrete, and rebar materials per the KBC standard. Results Display and Output. Nonlinear energy component output is now available per group for nonlinear load cases. Database Tables. An enhancement was made to add new capability to perform filters and sorts in displayed database tables by right-clicking in the table column headers. Release Date: 03 Sep New Database Tables. Tables have been expanded to completely define the model and results.
Most model-definition tables can be edited interactively. Exported tables can be edited and re-imported to define a new model or add to an existing model. Added Australian code AS Added Korean code KBC , including seismic design requirements. Design by Russian code SP Added Turkish code TS R , including seismic design requirements. Shear Wall Design. Added Russian code SP The tracing of wall legs in 3D walls has been enhanced for handling intermediate cross walls.

Performance-Based Design. Enhanced Output. Faster frame and wall design for all design codes and materials when considering many load combinations that contain multi-stepped load cases, such as time history. Faster creation of the analysis model when previously meshed shell objects do not need to be re-meshed. Faster display of results from modal time-history load cases, including FNA, for large models with many modes.
Reduced size of results stored for direct-integration time-history load cases. The new database tables can be accessed for display in multiple formats.
