Finite-element modeling of a composite bridge deck

Abstract

Finite-Element Modeling of A Composite Bridge Deck Suraj Suraj Fiber Reinforced Polymer (FRP) materials are being widely used for structural applications, an example being bridge decks. In this study a finite-element model using the software ANSYS is developed for an 8"-thick low-profile FRP bridge deck (Prodeck 8) made of E-glass fiber and Polyester resin. The bridge deck is subjected to a patch load at the center and the finite-element results obtained in the form of deflections, strains, and equivalent flexural rigidity are compared with experimental results. A good correlation is found to exist between the finite-element results and the experimental results. A failure analysis, based on maximum stress, maximum strain and Tsai-Wu theories of the Prodeck 8 is carried and first ply failure is determined. Finally, the Prodeck 8 is evaluated for critical load by performing a buckling analysis. I would like to express my sincere gratitude and appreciation to Dr. Nithi T. Sivaneri, my advisor and committee chairman. His contributions are too numerous to mention, but much of the success of the project is due to his guidance and these indispensable contributions will never be forgotten. I would like to thank the remainder of the advisory committee, Dr. Hota V. GangaRao for his valuable suggestions, feedback and insightful thoughts and Dr. Jacky C. Prucz for his suggestions and advice. Special thanks are also owed to Vimala Shekar for all her invaluable help and suggestions during the duration of the project. Many additional students and Faculty were very helpful during the course of this project, and their assistance is greatly appreciated.

Finite element analysis of low-profile FRP bridge deck (Prodeck 4)

“…Suraj Suraj (2005) has conducted analytical research on Prodeck 8 using ANSYS software. The analytical results obtained in the deflection analyses have showed excellent correlation with experimental results obtained by previous researcher.…”
