21.2.0_ETA_enhancement_video
Learn more about the latest enhancements in ETABS v21.2.0.
Design
21.2.0_ETA_AISC_360-16_360-10
Steel connection design is now available per the AISC 360-16 and AISC 360-10 codes. This includes Beam-Beam, Beam-Column, Column-Footing, welded, and bolted connections.
21.2.0_ETA_euro_steel_frame_corrigendum_2
Loading
21.2.0_ETA_turkish_code_2018_response_spec
The auto-seismic load pattern and response-spectrum function were added for the Malaysian National Annex of Eurocode 8-2004.
Structural Model
21.2.0_ETA__frame_hinge_assign_presets
The frame hinge assignment feature has been enhanced with four new preset hinge assignment distribution types:
- 1. Beam Column, which adds a moment or PMM hinge at the ends of the frame object.
- 2. Distributed Plasticity, which adds hinges along the length of the frame object based on a specified integration rule.
- 3. Equal Spacing, which adds hinges at a fixed spacing along the length of the frame object.
- 4. Continuous Support, which adds one hinge at the center of every frame element associated with the selected frame object.
Analysis
21.2.0_ETA_multi-thread_solver
An enhancement has been made to allow the “Number of (Internal) Threads for Analysis" setting to also control number of threads that can be used by the Multi-threaded Solver. This creates less competition for resources and can speed up analysis.
21.2.0_ETA_modal_damping
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
21.2.0_ETA_disable_sav_fiber_analysis_results
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.

21.2.0_ETA_exporting_pier_elements_Perform3D
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.

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.
