ETABS 2013

- The Auto-Relabel All option that was available in ETABS v9 has been restored.
- Russian material property and section property libraries have been added.
- ASCE 41-13 guidelines for performance-based design have been implemented for frame hinge definitions, performance-point calculations, and the behavior and acceptance criteria for panel-zones and BRBs (buckling-restrained braces).
- Masonry is now defined as a separate material rather than a type of concrete material.
- Multiple named mass-source definitions can now be created and used for different load cases.
- The Singapore National Annex has been added as an option to the Eurocode 8-2004 response spectrum function.
- Notional load patterns can now be based on snow loads as well as other gravity loads.
- User control is now provided for the handling of self-weight in the end offset portions of beam members.
- The speed of analysis has been increased for most load cases.
- The iteration strategy for nonlinear static and nonlinear direct-integration time-history load cases has been made more adaptive to typically improve convergence behavior and to reduce the time of analysis.
- The line-search algorithm is now available for nonlinear static analysis.
- Steel frame design for the Indian IS 800:2007 code now implements the changes in Amendment Number 1.
- The display of design input parameters for steel frame design overwrites has been enhanced.
- Canadian design codes (i.e., CSA A23.3-04 and CSA S16-09) now include snow loads in the default design combinations.
- Multiple enhancements have been made for composite beam design affecting the control of the design process, the look and functionality of the interactive design form, the format and content of the output, and other improvements.
- Shear wall design per the Indian IS 456:2000 code now allows separate control in the major and minor directions for enforcing the minimum eccentricity due to slenderness.
- Several database tables have been added or have had their content expanded, including the listing of object unique names where applicable.
- Table set definitions are now saved in the text model file.

- Concrete frame design and shear wall design using the AS 3600-09/NZS 3101-06 codes have been updated for Amendment No. 3 in 2011 affecting the seismic load combinations.
- Multiple enhancements have been made to shear wall design using the Eurocode 2-2004 code for the uniform-reinforcing and section-designer section options.
- The output table Modal Direction Factors, primarily used for Chinese design, has been enhanced to include the contribution of all mass in the structure, not just the mass in rigid diaphragm constraints.
- Database tables can now be exported to an XML file that can be opened by Microsoft Access, allowing the export to Access on machines that do not have it installed.
- The loads from staged-construction load cases can now be exported to SAFE.
- Multiple enhancements have been made to the import of .DXF files for floor plans, 3D models, and grid systems.
- Multiple enhancements have been made to the import and export of IFC 4 files.
- Multiple enhancements have been made to the import of SDNF files.
- Multiple enhancements have been made to the import of CIS/2 files.
- Many additional Open API functions have been implemented.
