RPI Master’s Project Proposal Stephen Ganz – 5/15/2012 Structural Analysis of Bridge Gusset Plates: Steel vs. Composite

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

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

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.

Expected Outcomes Composite gusset plates may offer possible strength advantages over steel. Resources Required Microsoft Office Abaqus/CAE (Finite Element Analysis Software) Mathcad
