ETABS v29 Enhancements
- The special requirements applied to the steel beam-column connections using the proprietary SidePlate® Systems have been updated to the latest version.
- The Korean common rebar set is now available when defining reinforcing bar sizes.
- Auto lateral loading has been added per the Korean KDS 41 17 00:2019 code, including seismic load and response-spectrum functions.
- Auto lateral loading has been added per the NTC 2018 code, including wind load, seismic load, and response-spectrum functions.
- The event-to-event analysis method has been improved for better handling of equilibrium unbalances. Additional controls are available for this non-iterative method.
- The speed of solution using the multi-threaded solver has been substantially increased for direct-integration time-history and other multi-step load cases.
- The recovery of plotted and tabular results from nonlinear static and direct-integration load cases is now significantly faster. Results include deformed shape, force and stress values, and hinge states.
- The parametric PMM hinge has been enhanced to provide better convergence behavior in sensitive systems.
- Short-term and long-term cracked-deflections can now be calculated for concrete floors. The rebar used for the cracking calculation is based on either provided rebar, designed rebar, or a quick rebar overwrite.
- Numerous enhancements have been implemented for Russian SP 16.13330.2017 steel frame design.
- Concrete frame design has been added per the ACI 318-19 code.
- Composite column design has been added per the AISC 360-16 code.
- Shear wall design has been added per the ACI 318-19 code.
- Slab design has been added for reinforced-concrete and prestressed (PT) slabs per the following codes: ACI 318-19 and AS 3600-2018
- The automatic tabular output after analysis can now be directed to multiple files. Each file can produce a different set of tables and can apply to a different group.
- Perform®3D model files can now be imported into ETABS. Most elements, cross-section properties, mass, loads, and load cases will be imported and translated. Certain types of nonlinear components will also be transferred, and a report will be produced of what was translated.
- Perform®3D model files can now be exported from ETABS. Most structural objects, properties, loads, and load cases will be exported and translated. The ETABS model to be exported must meet modeling requirements of Perform®3D. A report will be produced of what was translated.
