MC3D – Evolution of Segmental Bridge Software by Joseph P. LoBuono, P.E.
Article describes how one MC3D user has successfully used the Geometry Control program on multiple concrete precast segmental projects. The author describes basic implementation of the match-casting process.

Mix-Match Software Juggles Materials by Tom Sawyer
Article describes the release of Bridge Designer II (BD2) version 3.5. BD2 V3.5 implements theoretically correct structural behavior of composite sections, used for example for the time-dependent analysis of differential creep and shrinkage stress redistributions in “spliced-girder” type bridge structures with cast-in-place concrete slabs.
NCHRP Report 517
National Highway Cooperative Research Program by the Transportation Research Board of the National Academies
Report contains the findings of research performed to develop recommended load and resistance factor design procedures for achieving longer spans using precast prestressed concrete bridge girders. Standard details and examples illustrating the design of three typical bridges were also developed. The material in this report will be of immediate interest to bridge designers.

The Strutted Box Widening Method for Pre-stressed Concrete Segmental Bridges
Stantec Consulting used BD2 and BD2GUI to perform parametric study of span-by-span and cantilever bridge models. BD2 was used for detailed analysis of time-dependent construction stages. In this article author Ken Shushkewich presents the “strutted box widening method, “a system that allows a two-lane segmental bridge to be designed and constructed so that it can be easily widened into a three- or four-lane bridge at any time in the future”.

New Bridge Design Add-on Speeds Access to Plans A new graphical user interface for an established bridge analysis software package is enabling bridge designers to more quickly see the results of their work. San Diego-based Interactive Design Systems, which developed Bridge Designer and Bridge Designer 2 in the 1980s primarily for designing pre-stressed concrete bridges, recently introduced BD2GUI, an add-on interface for BD2 that allows users to input and display data graphically.
Bridge Design & Engineering – Q1 1999
New Software Solves Problems – US software specialist Interactive Design Systems has just launched a graphical interface for Bridge Designer II, its analysis and design program for concrete post-tensioned segmental and cable stayed bridges. The snappily-titled BD2GUI provides bridge engineers with access to data in the Bridge Designer RDMS database.
BD2 uses basic matrix structural analysis formulation, combined with time-dependent material properties to carry out a time simulation of a structure under construction. During this process all stress conditions are checked at every construction step and in service, claims IDS.
