SAP2000 – V14 – Features & Enhancements List

Computers & Structures, Inc. is proud to announce the release of SAP2000 V14. The innovative enhancements in this version are categorized below. This fully integrated product for the modeling, analysis and design of structures continues to be available in three levels: Basic, Plus and Advanced.

Nonlinear and Pushover

• A nonlinear, layered shell element using a directional material model has been added for
  pushover analysis of shear-wall structures and similar applications. A Quick-Start option is
  provided for easy modeling of reinforced concrete sections.
  Show me Nonlinear Shearwall capabilities

• Plot functions have been added for shell layer stresses.

  changed to improve convergence.

Dynamics

• Material-based damping is now available for linear and nonlinear direct-integration
  time-history analysis.
• Material-based damping is now available for steady-state and PSD analysis.
• Stiffness-proportional damping now uses initial stiffness instead of tangent stiffness to
  improve the consistency of results and convergence behavior.

  and general use.
• Base reactions for response-spectrum and modal time-history analysis have been improved
  for springs and grounded link supports to better capture missing-mass effects.
• Base reactions no longer include constraint forces at restraints, for consistency.

Bridge Modeling and Design

• AASHTO LRFD 2007 superstructure design for precast concrete composite sections has
  been implemented. Checks include: stress, flexure, and shear (using MCFT).
  Show me how Automated Seismic Design of Bridges works

• Fully automated bridge design check per AASHTO Guide Specifications for LRFD
  Seismic Bridge Design 2009 has been implemented, including pushover analysis
  when required.

  LRFD 2007 superstructure flexural design check for prestressed concrete box girder sections.

• Variable reference-point location along the length of the bridge superstructure is
  now available.
• Alignment of shell local axes in generated bridge models has been enhanced.
• The longitudinal discretization of bridge models is now more uniform in complex models.
• Tendons modeled as elements now allow elastic, creep, shrinkage, and steel-relaxation
  losses to be directly specified.
• The displacements for constrained joints in staged construction are no longer updated for   deflection until they are actually added to the model.

New Design Code Related Enhancements

• Eurocode-2 2004 concrete frame design added, without seismic provisions.
• Eurocode-3 2005 steel frame design added, without seismic provisions.
• Australian concrete frame design per code AS 3600-2001 added, including
  seismic provisions.
• Multiple enhancements made for Indian concrete frame design per code IS 456-2000.
• Multiple enhancements made for Chinese 2002 concrete frame design.
• Multiple enhancements made for Chinese 2002 steel frame design.
• Auto-lateral loads added for Eurocode: Wind, Seismic, and Response-spectrum.
• Auto-lateral loads added for Australia: Seismic and Response-spectrum.
• Auto-lateral loads added for New Zealand: Seismic and Response-spectrum.
• Other Enhancements to the Graphical User Interface (GUI) Multiple enhancements have been
  made to the graphical display for clarity and speed.
• Multi-stepped static analysis of Bridge Live loads acting on frame elements is now available in
  Plus/Advanced levels without the Bridge license for modeling crane loads, footfall, etc.
• Single-stage construction cases starting from zero are now available in Plus/Advanced levels
  without the Staged-construction license for modeling separate gravity and lateral
  configurations, different support conditions, etc.
• The import of StruCAD*3D data files is now available.
• New and updated API functions have been implemented. 

Minimum and Recommended System Requirements

• Processor: Minimum: Intel Pentium 4 or AMD Athlon 64. Recommended: Intel Core 2 Duo,
  AMD Athlon 64 X2, or better (see notes 1 and 2 below)
• Operating System: Microsoft® Windows XP with Service Pack 2 or Microsoft® Windows
  Vista, 32- and 64-bit versions. (see notes 3 and 4 below)
• Memory: Minimum: 1 GB for XP O/S, 2 GB for Vista O/S. Recommended: 2 to 4 GB for
  32-bit O/S, 4 GB or more for 64-bit O/S. (see note 5 below)
• Disk Space: 6 GB to install the program, additional space required for running and
  storing model files and analysis results.
• Video Card: Supporting 1024 by 768 resolution and 16 bits colors. Recommended: discrete
  video card with ATI / NVIDIA GPU & dedicated graphics RAM. (see note 6 below)

Notes:

1) To be able to take advantage of the features of the newer CPU's, SAP2000 V14 will
    not run on some of the older CPU's from Intel and AMD. A CPU that has SSE2 support
    is now required.

2) SAPfire® Analytical Engine now includes a multi-threaded solver that can take
    advantage of the newer multi-core CPUs.

3) Support for Microsoft® Windows 2000 and Microsoft® Windows NT has been discontinued.
    Microsoft® Windows XP without Service Pack 2 may cause unexpected problems
    when running SAP2000 V14.

4) With a 64 bit operating system, SAPfire® Analytical Engine can utilize more than 4 GB of
    RAM, making it possible to more efficiently solve larger problems.

5) The problem size that can be solved & the solution speed increases considerably with more
    RAM. Vista requires more RAM than XP for the operating system itself.

6) OpenGL graphics mode fully utilizes the hardware acceleration provided by a GPU &
    dedicated graphics RAM.

Significant New Features

• The capability to export a slab model to SAFE V12 has been implemented. This will be    supported by SAFE 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.

• The Norwegian national parameters have been implemented for auto seismic loading    according to the “Eurocode 8” code.

• The API 4F automated wind load has been enhanced to include a shielding factor.

• Steel frame design for the “NORSOK N-004” code, including punching checks, has been
   added to the Offshore module. The design of non-tubular sections is in accordance with
   Eurocode 3-2005 with the Norwegian National Annex.

• The Norwegian national parameters have been implemented for concrete frame design using    the “Eurocode 2-2004” code and steel frame design using the “Eurocode 3-2005” code.

• The 3-D rotation command in the graphical user interface has been improved for working in    zoomed-in regions.
