RPI Master’s Project Proposal Stephen Ganz – 5/15/2012 Structural Analysis of Bridge Gusset Plates: Steel vs. Composite
2
Gusset Plate Applications Gusset plates are used to join structural members such as beams and are typically made from steel. Specific Applications: –Bridges –Building Frames –Roofing –Cranes
3
Problem Description The objective of this project is to compare the performance differences in metallic and composite plates by performing structural analyses on a Warren truss bridge. Performance will be evaluated based on stress and deflections. –Loading will be based on Department of Transportation and CT Bridge design manuals. Warren Truss Bridge
4
Methodology/Approach On paper, construct a bridge that reflects actual dimensions and loading. In finite element analysis software, create a 2-D model representative of the bridge constructed of gusset plates, loads and constraints. Run analyses using steel and composite material properties. Compare results. Optimize composite structure.
5
Expected Outcomes Composite gusset plates may offer possible strength advantages over steel. Resources Required Microsoft Office Abaqus/CAE (Finite Element Analysis Software) Mathcad
