• Abstract:
  A number of full-scale tests have been carried out in the laboratory focused on the shear ; performance of simulated precast concrete deck panels (PCP). Shear tests were carried out to ; simulate the type of loading that will be applied to the deck panels as they are engaged as a ; bracing element. As part of the research study, two different finite element models were ; developed to improve the understanding of the behavior of the concrete deck panels as well as ; the members that are to be braced by the deck panels. The two models consist of a detailed ; model as well as a simple model. The purpose of the detailed model is for studying the impact of ; details on local stress concentrations in the panels so as to understand the potential for cracking ; or crushing of the concrete in isolated regions. The purpose of the simple model is to represent ; the stiffness and strength of the concrete deck panel for parametric studies are larger ; girder/bridge systems. Both of these finite element analytical models represent the most recent ; PCP/connection system tested in the shear frame and were developed using the commercial ; software program Abaqus/CAE 6.13-1. This detailed model was constructed to gain insight in ; the behavior of the PCP/connection system under the loads applied in the shear frame test to help ; refine the connection system if necessary. The simple model consists of a simple truss system ; that represents the PCP/connection system. This simple model will be useful for describing the ; PCP/connection system in the parametric finite element modeling of steel I-beam, steel tub ; girder, and straight and horizontally curved precast concrete box girder systems. Furthermore, ; the truss model will be used to represent PCP/connection systems in UT Bridge. UT Bridge is a ; software program that was developed as part of TxDOT research project 0-5574 and allows ; engineers to quickly developed analytical models of curved steel girder systems during ; construction. The program is currently at version 1.6; however, a major upgrade is in the works ; for the program that will be released at version 2.0. The simple model that is being developed as ; part of this project will be utilized in the program, which will provide an easy means for ; engineers to account for the contribution of the deck panels during the analysis of the erection or ; deck construction stages.
