This TxDOT-customized version of PGSuper is versatile, user friendly, Windows-based software for the design, analysis, and load rating of multi-span precast-prestressed concrete bridge beams/girders in accordance with the AASHTO LRFD Bridge Design Specifications (thru the 9th Edition, 2020) and by TxDOT design policies and guidelines. Properties of TxDOT standard I-girders (TxGirders), U beams, slab beams, decked slab beams, box beams, and X-beams and TxDOT specific design criteria are included in templates and libraries published by TxDOT on a server accessible via the Internet. Thus, the software is capable of periodically updating the installed templates and libraries with the most current versions published by TxDOT. Though these templates and libraries are subject to change, the user may save PGSuper project data with its associated templates, libraries and settings in a .pgs file which can subsequently be opened by PGSuper preserving the templates, libraries, settings and design data of the bridges as originally designed.
Custom defined beam shapes that fit within each family of girder types supported by PGSuper can also be added to the user copy of the templates, thereby extending the girder shapes that the user can design, analyze, and load rate with the program.
The flexural design feature computes the required number and pattern of prestressing strands and the minimum required release and final concrete strengths. Specification checking evaluates girders for compliance with strength, serviceability, and detailing criteria. Horizontal and vertical shear design, analysis, and load rating is also facilitated.
UT Lift is an easy to use, macro-programmed Excel spreadsheet for determining the behavior during lifting of straight and horizontally curved steel I-girders with one crane and two lift clamps.
UT Bridge is a 3-dimensional finite element program for the analysis of curved steel I-girders and steel tub girders. Computations include linear elastic analysis (first-order and second-order) and eigenvalue buckling analysis for both girder erection and concrete deck placement.
Abstract:Coastal bridge damage has become a severe issue of concern in the recent past with the destruction of a considerable number of bridges under the impact of waves during tsunami and storm surges. These events have become more frequent, with waves reaching the bridge deck and causing upliftment and destruction. Past studies have demonstrated the establishment of various theoretical equations which works well for the submerged deck and regular wave types but show much scatter and uncertainty in case of a deck that is above still water level (SWL). The present study aims to generate a solitary wave to represent an extreme wave condition like a tsunami in the numerical wave tank modeled using the open source computational fluid dynamics (CFD) model REEF3D and to study the vertical impact force on the coastal bridge deck. A parametric study is carried out for increasing wave heights, girders spacing and depth for varying airgaps to analyze the effect of these parameters on the peak vertical impact force. It is observed that increasing the girder spacing and girder depth is effective in reducing the peak vertical impact force for the cases considered.Keywords: air entrapment; Airgap; extreme wave; computational fluid dynamics (CFD)
