The innovative and revolutionary new ETABS is the ultimate integrated software package for the structural analysis and design of buildings.
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.
An enhancement has been made to the Eurocode 3-2005 steel frame design to update the design according to Corrigendum 2 released in 2009.
The TSC-2018 response-spectrum function has been enhanced to allow specification of the R, D and I parameters.
The auto-seismic load pattern and response-spectrum function were added for the Malaysian National Annex of Eurocode 8-2004.
The frame hinge assignment feature has been enhanced with four new preset hinge assignment distribution types:
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.
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.
Enhancement added for exporting Non-Linear links from ETABS to Perform3D. Following links types are handled:
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.
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.
