Imbsen Software Systems

WinBDS analyzes or designs orthogonal bridge frames and is applicable to the majority of concrete bridges being designed today.
CROSS SECTIONS may by specified by using a predefined, standard box girder superstructure shape or by adding or subtracting geometrical parts using predefined part codes.

LIVE LOADS can be automatically generated for the AASHTO HS20-44 and the California P13 truck by simply giving the number of live loads lanes may be applied to the structure by describing the axle loads, distance between axles and number of live load lanes. Uniform lane loads can be defined with moment and shear riders. Other automatically generated live loads include the Cooper Loading and a user defined vehicle of up to 97 axles.

PRESTRESSED CONCRETE analysis and design capabilities include: Continuous prestress, Simple span prestress, Segmental prestress, 100 prestress cable paths per frame, 3D cable friction losses, Primary and Secondary effects, Cross-section analysis, Ultimate capacity check, AASHTO shear requirements, Tendon elongations, and calculation of AASHTO long-term losses.

OUTPUT results are organized in the same order as the input data. All input data is echoed in the output reports. Output reports include section properties, dead load and additional fixed loads results, live load force envelopes, prestress results including required P-Jack, mild steel requirements, and shear design stirrup requirements. Additional reports are generated for the Rating Subsystem and Prestresed Precast Girder Subsystem.

GRAPHICAL DISPLAY of moment and shear envelopes are available after an analysis has been performed. Additional plots are available for deflections, top and bottom fiber stresses, prestress force, prestress cable path and influence lines. These plots can be displayed for all spans in the bridge or for an individual span or for any sequential list of spans. Where applicable, the plots include the different trials that are available, such as: dead load, added dead load, live load no. 1 (both negative and positive envelopes), prestress, etc. These loads can be plotted individually or combined into one load case.
