The following Enhancements have been implemented for CSiBridge 2015 v17.0.0:
The responsiveness of the user interface has been improved.
The DirectX graphics functionality has been enhanced.
A friction-spring hysteretic damper has been implemented as a new link property. The force-displacement relationship exhibits linear slipping stiffness when loading, but unloads with a smaller slipping stiffness. A pre-compression displacement and a displacement stop-limit may be specified.
A bilinear Maxwell damper has been implemented as a new link property. This device is a linear spring in series with a dashpot whose force-velocity relationship exhibits bilinear viscous behavior, typical of certain oil dampers having a relief valve.
Improved convergence behavior and increased speed for nonlinear static and direct-integration time-history analysis.
Increased speed of moving load analysis by parallelization.
Superstructure design checking has been extended to include composite bridge superstructures with steel U-girders according to the Canadian CAN/CSA-S6-06 code.
Superstructure design checking has been extended to include composite bridge superstructures with steel U-girders according to the Indian IRC-2011 code.
Superstructure design checking has been implemented for concrete superstructure sections according to the Russian SNiP 2.05.03-84 code. Superstructure types supported include prestressed concrete box girders and composite sections with precast I-girders and U-girders.
Superstructure design reports have been enhanced to include step-by-step detailed output, including equations and code references. These are currently available for AASHTO LRFD 2007 and 2012, for multi-cell concrete box shear and flexure checks and precast composite I-beam shear and flexure checks.
A traditional menu has been added as an alternative to the ribbon. Users can switch between the two options.
The ribbon style has been updated to be similar to current Microsoft applications.
Other minor enhancements.

On Saturday, April 5, 2014, over 1200 friends of CSI convened at San Francisco City Hall in San Francisco, California, to commemorate the 39th anniversary of Computers and Structures, Inc. Attendees included prominent members of the structural engineering profession, professors, researchers, civic leaders, lawyers, doctors, artists and others who travelled from all over the world to be at the event! The sparkling celebration, featuring a Sixties theme, was the culmination of CSI's international dealer conference, which was held at the Marriott Union Square and was attended by CSI software representatives from around the globe.

Significant enhancements include:
Steel frame design has been added according to the Norsok N-004 2013 code.
Steel frame design according to the API RP 2A-WSD 21st edition code has been updated for supplements 1, 2 and 3.
Auto lateral wind load has been added according to the API 4F 2013 code.
The Chinese section-property database files have been enhanced by adding new sections.
A bilinear Maxwell damper has been implemented as a new link property. This device is a linear spring in series with a dashpot whose force-velocity relationship exhibits bilinear viscous behavior, typical of certain oil dampers having a relief valve.
A friction-spring hysteretic damper has been implemented as a new link property. The force-displacement relationship exhibits linear slipping stiffness when loading, but unloads with a smaller slipping stiffness. A pre-compression displacement and a displacement stop-limit may be specified.
The specification of the notional size used for time-dependent creep and shrinkage analysis has been enhanced to now be specified with the frame and shell section properties instead of with the material property.
A new staged-construction operation “Change Section & Age” is now available allowing specification of the “Age at Add” when changing frame sections or shell sections.
Table output can now request the correspondence between the response components at a single location for additive-, range-, and enveloping-type load combinations. Results that admit correspondence includes most displacement, force, and stress response quantities.
The import of primary data from SACS data files is now available.
