    LRFD
    • For shear designs done by the modified compression field theory, in accordance with AASHTO LRFD 2005, the average shear stress was computed incorrectly. The shear capacity computations have been corrected.

    Archive Version: 2.2 - October 01, 2004
    General
    • Removed support for the IDispatch interface. IDispatch methods are very slow and adversely effected the overall performance of the libraries. As a consequence collections no longer support Visual Basic's For Each construct or default properties. This is a binary incompatible change so any application depending on WBFL components must be recompiled.
    • Modifications to support the latest versions of PGSuper and PGSplice
    RCCapacity
    • Made some speed improvements to the NLSolver component
    • Improved convergence tolerance checking and added a maximum iteration count to the NLSolver object. If the solver cannot find a solution after 100 tries, the iteration stops.

    Archive Version: 1.1 - Update 3 - January 03, 2002
    General
    • The Alternate Route Project software licenses have been updated to offer the same disclaimers for people who modify source code written by others and for people to contribute original source code and software to the project. The ARPNotice object has been updated to use the latest licenses.
    Geometry
    • Made the geometry objects persistable
    Archive Version: 1.1 - Update 2 - November 20, 2001

    COGO
    • Add support for locating lines tangent to two circles
    • The begin vertical curve elevation was computed incorrectly in a profile. This problem has been corrected.
    WBFLTools
    • The Alternate Route Project software licenses have been updated to offer the same disclaimers for people who modify source code written by others as for people to contribute original source code and software to the project. The ARPNotice object has been updated to use the latest licenses.
    Archive Version: 1.1 - Update 1 - August 28, 2001
    General
    • Preview 1 Release of WBFL COGO. Coordinate Geometry library
    WBFL Fem2d
    • Added documentation for Coordinate Reference Frames
    WBFL Geometry
    • The points generated by IGeomUtil2d::DivideArc were incorrectly based on a clockwise arc. The points should be based on a counter-clockwise arc. This problem has been corrected.
    • The CreateParallelLine method of the GeomUtil object created parallel lines on the wrong side of the source line. A parallel line to the right of the source line is supposed to be created for a positive offset distance. A parallel line on the left of the source line was actually created. This problem has been corrected.
    • The Angle method on the IGeomUtil2d interface computed the angle formed by three points incorrectly. The document indicates that the computed angle is counter-clockwise. The method was computing a clockwise angle. The method has been updated to compute a counter-clockwise angle.
    WBFL Unit Server
    • Corrected typographical errors in documentation
