Many state DOT's make use of the Inverted Tee Bent Cap system in simple span precast-prestressed concrete girder bridges. PGSuper does not model any specific substructure system, but instead provides a flexible geometric description to accommodate inverted tee bent caps and virtually every other substructure system. This tutorial explores how to define the connection geometry for an inverted tee pier cap.

In the second of a three-part series, we model a three span interchange ramp bridge. The bridge is located in a transition between a straight portion of the alignment and a curved portion. The deck width tapers to accommodate the geometry of the site and the roadway. The seven W42G girders are uniquely framed in every span..
WSDOT posted PGSuper Version 2.1.1 yesterday. It can be downloaded from www.wsdot.wa.gov\eesc\bridge\software.
New stuff in this release consists mostly of minor bug fixes to 2.1. However, there are two issues that deserve attention:
1) A bug where the effective flange width was computed as twice the correct value for bridges using Deck Bulb Tee's, Double Tee's (plain type), Double Tee's (WSDOT type), and Ribbed Girders. This bug will cause non-conservative designs for these bridge types.
I did my best to fill out the table based on data from product brochures but since I don't own either of the latter programs, details are missing. Any information that you may have to help complete the table will be much appreciated.
A new tutorial: Advanced Geometrics - Part 1
In this first of a three-part series, we explore how to create a multi-span tapered bridge on a horizontally curved alignment.
