Design
An enhancement has been made to the Eurocode 3-2005 steel frame design to update the design according to Corrigendum 2 released in 2009.
Analysis
An enhancement has been made to speed up direct-integration time-history load cases with additional modal damping specified for a large number of modes. For building structures, the higher-frequency modes typically respond statically to seismic and wind loading, and stiffness proportional damping is more efficient for the damping at high frequencies.
Output and Display
The option to disable saving of individual fiber results for Fiber P-M2-M3 frame hinges is now available. This can significantly reduce disk storage when individual fiber stress-strain results are not needed. Detailed hinge results will still be available, including the state and status of the hinge obtained from the fiber results.
Database Tables
The following "Analysis Results" database tables have been parallelized for increased speed during display or export: "Joint Displacements, "Joint Displacements - Absolute", “Joint Drifts", "Pier Forces", "Pier Force Status", "Spandrel Forces, and "Spandrel Force Status". In addition, individual table progress will now be displayed in the status bar while filling any of the “Analysis Results” tables for display/export. The progress bar is effective for tables that take significant time to display/export.
Import and Export
ETABS models exported to Perform3D now include shell uniform loads in the global coordinate system. These loads will be exported to Perform3D as lumped nodal loads on the nodes which form the shell elements.
Import and Export
For ETABS models exported to Perform3D, frame objects that are assigned a Pier or Spandrel label will be exported to Perform3D in separate element groups based on their Pier or Spandrel label names.
Import and Export
ETABS models exported to Perform3D now include Line and Quad gauge elements. Translational type line gauges in ETABS will be exported as Perform3D Axial Strain Gage (2-node) components. Rotational type line gauges in ETABS will be exported as Perform3D Rotational Gage, Beam Type (2-node) components. Shear type quad gauges in ETABS will be exported as Perform3D Shear Strain Gage (4-node) components. Rotation type quad gauges in ETABS will be exported as Perform3D Rotation Gage, Wall Type (4-node) components.
Loading
Loads assigned to null lines and null areas applied in any local or global direction are now transferred to the underlying structural floors. In earlier versions only loads in the gravity direction were transferred.
Database Tables
Performance-check definitions can now be edited when the model is locked and selected for associated tabular output.
Loading
An enhancement was made so temperature loads on overlapping area objects will be applied additively. Previously, temperature loads assigned to the slab would not affect overlapping drop panel objects.
Loading
Pattern Live load is now available as a type of loading, allowing manual assignment of live loads to different regions of the structure that will be automatically varied in load combinations to produce the maximum response.
Loading
Pattern loading, including Auto-Pattern loading, can now be assigned to slabs. Auto-Pattern loading automatically creates multiple load patterns from specified live loads on slabs, each loading a single slab panel.
Analysis
The analysis engine has been optimized for newer AMD CPUs.
Design
Several enhancements have been made to Eurocode 2-2004 concrete frame design, including improved calculation of slenderness effects and new national-annex values of TanTheta for shear design.
Design
Slab design for IS 456:2000 now provides an option increase longitudinal reinforcement in slabs as needed to avoid shear links in the slab.
Design
Several enhancements have been made to steel frame design for the Eurocode 3-2005 and NTC 2008/2018 codes, including improved calculation of Mcr, and results output referred to y-z axes rather than major-minor axes.
Integration with Perform 3D
Imports from Perform3D now support nonlinear components "Moment Hinge, Rotation Type", "Shear Hinge, Displacement Type", and "P-M2-M3 Hinge, Concrete Rotation Type". Additionally, the following load types can now be imported: Self Weight, Nodal Loads, and Element Loads.
Design
Concrete beam and strip-based slab design now allow control over including or excluding axial compression in flexural design if the axial compression reduces the required reinforcement. Axial tension and axial compression that increase the required flexural reinforcement are always considered. For post-tensioned construction all axial load is always considered.
Design
Eurocode 2-2004 concrete frame design has been updated to consider the extra longitudinal rebar due to shear.
Import and Export
Mapping of Revit element Unique IDs to ETABS Object GUIDs can now be exported to Excel.
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.
Detailing
ETABS has been enhanced for compatibility with CSiXCAD™ a new plug-in from Computers and Structures, Inc., for the detailing and documenting of steel and concrete structures within AutoCAD® or BricsCAD®. Working with building models that were analyzed and designed in ETABS, CSiXCAD can automatically create plans, elevations, schedules, and BIM models. Drawings can be updated to reflect changes to the ETABS model and design results, while retaining drafting changes made to the drawings themselves. Learn More
