BridgeSight Signs Contract With PennDOT for PAPIER Maintenance

July 1, 2001 - BridgeSight Software signs a multi-year contract with the Pensylvania Department of Transportation to perform software maintainance and updates on the PAPIER program.

PaPier is a large-scale FORTRAN program that implements the AASHTO LFD or LRFD Specifications for the analysis of concrete bridge substructures. . PAPIER is highly configurable and incorporates many features such as support for the AASHTO LFD and LRFD specifications as well as METRIC and SI units. PAPIER has the most thorough implementation of LFD/LRFD loading undertaken in a bridge design program.

Washington DOT Releases PGSuper 1.0

September 7, 2000 - PGSuper version 1.0 is released. Rick Brice at WSDOT and Richard Pickings at BridgeSight Software have combined forces to deliver this state-of-the-art new program.

PGSuper is an MFC-based, Windows program for the design of precast girder bridges based on the AASHTO LRFD Specifications. PGSuper has a highly interactive graphical user interface that is designed for use in a production-engineering environment. PGSuper can be used to design and check precast-prestressed girder bridges in accordance with the AASHTO LRFD Bridge Design Specification and/or WSDOT criteria.
The flexural design feature computes the number and configuration of prestressing strands and the minimum required concrete release strength. The shear design feature determines the number, size, and spacing of transverse reinforcement for vertical shear, horizontal shear, bursting, and strand confinement. Specification checking evaluates girders for compliance with strength, service, and detailing criteria. Girders are evaluated for stresses and stability during handling and transportation. Temporary prestressing to control camber, improve stability, and reduce concrete release strengths may also be input. The capabilities and constraints of local fabricators have been accounted for in this software product. PGSuper™ has been designed to allow for future expansion and updating.
