Multiscale and Multi-Hazard Investigation of Fire on Suspension Bridges

Prof. A. Brügger is seeking BS and MS students to do research in the Carleton Lab over the summer. The work will be related to one of the two projects

· Modeling Fire Hazard of Suspension Bridges The aim of this project is to build a constitutive numerical model that will be tuned/optimized with data currently being generated at the Carleton Laboratory in various experiments. Student(s) will use ABAQUS to generate FEM models representative of the experimental system and subsequently validate them with experimental data. A broad forensic survey is also being conducted on bridge fire incidents around the globe.

· Quantifying Internal Mechanics of Bridge Cables using Neutron Diffraction The aim of this project is to understand the internal mechanics of parallel wire bridge cables, especially in the case of fracture of single wires in a strand. Student(s) will use ABAQUS to generate FEM models of experimental systems to better understand the internal force redistribution and stability of these strands when they undergo local failure.

The research project is flexible, allowing students to interact either on a remote, hybrid, or fully on-site manner. The group will meet via Zoom on a weekly schedule to share progress and brainstorm each other’s questions. Deliverables include regular progress reports, a final report, including relevant numerical models. The student will be closely advised and trained by a PhD student and/or Dr. William Hunnicutt. No previous research experience is necessary - just enthusiasm for experimental materials research!

Projects permitting, you may also be able to participate in the testing of real-life materials tests from actual structures!
