   V12.2 when it is released.

• Detailed design checking has been implemented for multi-cell prestressed-concrete
  box-girder bridge superstructures according to the “AASHTO LRFD 2007” code using
  Live-Load Distribution Factors. This is in addition to the whole-section design previously
  released. Design checks are available for stress, flexural capacity, and shear capacity using
  MCFT (modified compression field theory).

• Concrete frame design has been implemented using the AASHTO LRFD 2007” code.

• Significant speed improvements have been made to the generation of AASHTO/Caltrans
   frame hinges for pushover analysis.

• General improvements have been made to the automated bridge seismic design feature.

• The concrete U-girder frame section can now also be used to model steel tubs in the
  Bridge Modeler. Each section can be supported by a single bearing at the center, or two
  bearings at the edges of the girder.

• The modeling of steel-girder diaphragms for steel girder bridges has been improved to provide
   better support for the lower flange.

• Automated wind lateral loading for Australia and New Zealand has been implemented according
   to the 2002 AS/NZS 1170.2 code.

  response-spectrum load cases.

• Concrete frame design using code "ACI 318-08" has been implemented.

• Eurocode 8 seismic provisions have been implemented for concrete frame design using code
 “Eurocode 2-2004”.

• Eurocode 8 seismic provisions have been implemented for steel frame design using code
 “Eurocode 3-2005”.

• The Singapore National Annex to Eurocode 2 (NA to SS EN 1992-1-1 : 2008) has been
  implemented for concrete frame design using “Eurocode 2-2004”.

• Snow loads are now included in the automatic load combinations that are created for
  concrete design using codes "ACI318-02/IBC2003" and "ACI318-05/IBC2006". The
  documentation has been updated accordingly.

• The design load combinations created by the program for steel frame design code
 "CAN/CSA-S16-01" now include notional loads, if any have been defined.

• The shear design for “Eurocode 2 2004” has been enhanced to optimized for angle “theta” in
  Section 6.2.3 of the code.

• The identification of lateral load cases (seismic or wind) has been improved for nonlinear
  cases which may contain these loads. This affects the increase in allowables for some
  design codes.

• The design preferences for concrete, steel, cold-formed steel, and aluminum design have
  been enhanced to provide more control for the creation of internal design load combinations
  involving nonlinear and staged-construction static load cases.

• User-defined frame hinges can now be assigned to any frame section or any material.
  Previously, hinges could only be assigned to certain known section types, such as
  rectangular and circular concrete sections; steel pipes, tubes, and wide-flange sections;
  and Section-Designer sections.

• Displayed plot functions have been enhanced by adding the ability to plot forces for section
  cuts that have been defined using quadrilateral cutting planes. Previously only forces for
  sections cuts defined from groups could be displayed as plot functions.

• When displaying mode shapes graphically, the modal frequency is now displayed as well as
  the modal period.

• Improvements have been made to nonlinear direct-integration time history analysis to improve
  its speed and convergence.

• Three new options are now available for dividing frame objects using the command Edit > Edit
  Line > Divide Frames. They are (1) Divide at a specified distance from the I-end of the frame,
  (2) Divide at the intersection with a coordinate plane in the current coordinate system, and (3)
  Divide at the intersection with visible grid planes in the current coordinate system.

• An enhancement has been made to the graphical user interface so that the view no longer
  zooms out after certain operations, such as showing selection only, performing editing
  operations like deletion, and returning from the Bridge Modeler.

• The import and export of IFC files has been updated to include Schema 2x2, 2x3, and
  2x3_TC1, including the import/export of sections properties.

• The ability to export physical objects to IGES files has been added. Previously all objects
  were exported as FEM entities. Now you can choose either option. If you export as FEM,
  loads and properties are also exported. If you export as physical objects, only geometrical
  line and surface entities will be created, but properties and loads will not be exported.

• A new option to export a Perform3D Structure has been added. Most geometry, material
  and section properties, restraints, diaphragm constraints, groups, loads, and load cases
  are exported for frame and shell elements. Corresponding Perform3D members are created
  depending on the properties and assignments present on the individual SAP2000 members.
  Detailed hinge properties and other Perform3D-specific features must be defined
  in Perform3D.

• The Open API function that hides the GUI now also turns off the drawing functions for
  increased execution speed.


Significant enhancements included in SAP2000 v14.2.2:

• Steel-frame design has been implemented for the Australian design code "AS 4100-1998".

• The National Annex parameters for Sweden, Finland, and Denmark have been added for
  concrete frame design per code "Eurocode 2-2004" and for steel frame design per
  "Eurocode 3-2005".

• The sign of all results for hyperstatic load cases has been reversed at the request of
  several users.

• The installation has been changed so that it is no longer necessary for users to use
  the command "Run As Administrator" the first time they execute SAP2000 after updating to
  a new version of the program if they uninstall the previous version first.


Significant enhancements included in SAP2000 v14.2.3:

• The program level (Advanced, Plus, Basic) can now be chosen when starting the program
  using a command-line option.

• New Quick Materials have been added for common Indian steel, concrete, and rebar
  material properties.

  have been updated to the latest edition of the code.

• Modal time-history analysis for dynamic bridge loading now runs considerably faster.

• Multiple enhancements have been made for concrete frame design using Indian code
  IS 456-2000 for handling slenderness and P-delta effects.

• Eurocode 3-2005 steel frame design has been enhanced to provide more detailed reporting.

• The export to CIS/2 has been enhanced so that the resulting data files can be read by
  SDS/2, and now includes all frame offsets.


Significant enhancements included in SAP2000 v14.2.4:

• Concrete frame design has been enhanced to improve the smoothing of P-M-M interaction
  surfaces in those rare cases where they become non-convex due to kinks in the P-M curves.

• A new design overwrite has been added for steel frame design using the "Eurocode 3-2005"
  code. You may now use the "Is Rolled Section" parameter to indicate whether the member
  is rolled or welded. The assignment as rolled or welded affects the b/t ratio and therefore
  may affect the section classification. It may also affect the shear-area calculation.

• The limit on the number of nodes (joints) allowed for exporting a model to a SASSI file has
  been increased from 9999 to 99999. The exported files are still compatible with the older format
  if fewer than 10000 nodes are exported.
