Released 12-Oct-2022

Release Notes

Frame Design


The calculation of the C1, C2, and C3 factors has been improved, and more control has been provided, for the following codes and types of design:
  • Steel frame design per Eurocode 3-2005, Italian NTC 2008, and Italian NTC 2018
  • Cold-formed steel frame design per Eurocode 3 1-3 2006
  • Aluminum frame design per EN 1999:2007

Concrete Shell Design


Concrete shell design per Eurocode 2-2004 now includes a check for cracking in concrete and also the design of transverse shear reinforcement in accordance with Annex LL of Eurocode 1992-2:2005.

Structural Model


New and updated property libraries:
  • • New Indian frame-property library for steel sections
  • • Updated Chinese frame-property library
  • • New Canadian material-property library


Viscous dampers now support a fixed-length option to handle the change in stiffness due to inserting fixed-length devices into structural members of varying lengths.

Output and Display


Improved display of nonlinear hinge states and statuses.

Import and Export


Several enhancements have been made to the connection with Revit, including support for analytical links, structural column cardinal-point offsets, and the handling of vertical walls with sloping bases. These require the use of CSiXRevit 2023 with Revit 2023.

Application Programming Interface (API)


The Application Programming Interface (API) now offers more control for connecting to multiple instances of SAP2000, a new interface to simplify the development of plugins, and speed enhancements for external .NET clients.

Bug Fixes


Issues reported by users have been corrected.


Released 11-Mar-2022

Release Notes



The CSA A23.3-19 code has been added for concrete frame design.

The CSA S16-19 code has been added for steel frame design.


Concrete shell design per Eurocode 1992-1-1:2004 has been enhanced, including the ability to set design preferences and national annexes, improved iteration for determining the optimum amount of reinforcement, handling of variable-thickness shells, and the presentation of detailed results in tabular form.



Time-dependent behavior of concrete has been added for the AS3600-2018 code, including creep, shrinkage, and age-dependent stiffness.


The ability to enable/disabled the coupling between major bending, shear V2, and torsion is now available for channel and general sections.

23.3.0 | 23.3.1

Released 24-Sep-2021

Release Notes



Aluminum frame design has been added according to Eurocode 9.


Released 19-May-2021

Release Notes



Performance has been improved for models with frame elements in the presence of many load patterns. This includes speed increases in stiffness formation, event determination, and state-update operations. Nonlinear static, staged-construction, and nonlinear direct-integration time-history load cases will benefit the most.


The consistency of analysis results has been improved on Intel and AMD CPUs with an AVX2 instruction set, which includes most CPUs released in 2015 or later. This only affects sensitive or poorly conditioned models.



Aluminum frame design has been added according to the US 2020 Aluminum Design Manual. 

Database Tables


Performance improvements, by means of multi-threading, have been made for the recovery of results for frame hinge response tables.
