  • Stiffness-proportional damping now uses initial stiffness instead of tangent stiffness to improve the consistency of results and convergence behavior.
  • The rigid-response calculation in response-spectrum analysis has been enhanced for NRC 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.
  • Automated handling of secondary prestress force has been implemented for the AASHTO LRFD 2007 superstructure flexural design check for prestressed concrete box girder sections.
  • The AASTHO/USGS 2007 response-spectrum function has been added.
  • Variable girder spacing along the length of the bridge superstructure is now available.
  • 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  • The displacements for constrained joints in staged construction are no longer updated for deflection until they are actually added to the model.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

  • 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.

Notes: 

  • 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
  • SAPfire® Analytical Engine now includes a multi-threaded solver that can take advantage of the newer multi-core CPUs.
  • 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.
  • 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.
  • 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.
  • OpenGL graphics mode fully utilizes the hardware acceleration provided by a GPU & dedicated graphics RAM.
