Significant enhancements included in CSiBridge v15.0.1:
* A new option has been added for the modeling of I-girders in composite steel-girder superstructure sections. In addition to the existing options to model the I-girders as frame objects or as area objects (for both web and flanges), the girders can now be modeled using area objects for the webs and frame objects for the flanges.
* A new bridge seismic design check has been added to the Chinese version that follows the Chinese code JTG/T B02-01-2008, "Guidelines for Seismic Design of Highway Bridges".
* Bridge design for prestressed concrete box girder superstructures using Chinese code “JTG-D62-2004” in the Chinese version has been updated as follows: (1) The effect of existing longitudinal rebar is now accounted for in flexural design. (2) A new design check has been added for tendon stress.
* The Chinese 2002 building design codes are available for concrete and steel frame design in the Chinese version.
* 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.
