CEEM Students Receive Thornton Tomasetti Awards

Jul 16 2018

The CEEM department is pleased to announce that Longxi Luo and Joanna Zou have been awarded scholarships by the Thornton Tomasetti Foundation.

Longxi Lou

Longxi received his Master of Science degree at Columbia in May 2014 and he is currently completing his PhD under the advisement of Prof. Maria Feng.  Prior to attending Columbia, Longxi earned his Bachelor of Engineering degree in Civil Engineering at the University of Science and Technology Beijing.

PhD student Longxi Luo has been awarded a $5,000 Thornton Tomasetti Student Innovation Fellowship in recognition of his exceptional submittal for innovative research to investigate autonomous Bayesian updating of a frame structure using vision-based displacement measurements.  This award is intended to further innovation in the structural engineering and applied mechanics practice.

For this project, Longxi proposed an innovative framework for Bayesian model updating of structures using displacement measurements from a non-contact vision sensing system. The vision sensing system is simply composed of a computing unit enabled by computer vision techniques, and multiple cameras, every one of which can measure displacements of multiple locations simultaneously from a long distance with easy installation and low cost. If achieved, the project can provide a framework for autonomous updating of the finite element (FE) model, initially developed by the design engineers, to match the current state of the real building using measurements from easy-to-setup cameras. Engineers will be able to monitor the state of the structure and its changes, so they can take preventive actions to avoid serious monetary loss or even structural failure. The difficulties associated with vision-based model updating such as model updating based on output-only displacement measurements will be addressed. The framework will be evaluated on a 3D four-story eight-feet-tall steel frame structure.

Joanna Zou, who received her Bachelor of Science degree in May 2018, has been named a recipient of the $10,000 Thornton Tomasetti Foundation National 2018-2019 Scholarship in recognition of her exceptional academic success and demonstrated interest in the integration of engineering and architecture.

Joanna will pursue research in structural engineering during her Master's degree at Stanford University starting in the Fall 2018 semester.  She is currently completing a summer internship working in seismic risk assessment and finite element analysis with the Advanced Technology & Research group at Arup.
