A Seismic Interferometry Approach for Rapid Post-Event Damage Identification of Building Structures

January 2016 - September 2016

This innovative research proposes the development of a fast damage identification approach for building structures using a method similar to seismic tomography. The funding for this research was provided through the Caltech Terrestrial Hazard Observation and Reporting (THOR) program.

Identifiability Assessment of Structural Models using an Information-Theoretic Approach

February 2015 - September 2015

This research aimed at providing an innovative framework for senor placement to ensure the successful performance of nonlinear structural system identification methods. 

Output-only Nonlinear System Identification of Civil Structures using Sparse Seismic Measurement Data

August 2014 - September 2015

This research represents another innovation in my Ph.D. work. I have originally proposed and developed an innovative framework for output-only nonlinear system identification of civil structures based on nonlinear finite element (FE) model updating, utilizing only the measured structural response to earthquake excitations.

Structural Health Monitoring and Damage Identification of Civil Structures Based on Nonlinear Finite Element Model Updating using Bayesian Inference Framework

July 2013 - Jan 2015

This project constitutes the flagship and chief novelty of my Ph.D. work. Through this cutting-edge research, we are developing a groundbreaking methodology that can draw a new pathway in structural health monitoring and damage identification practice. 

Pre-Test Nonlinear Finite Element Response Simulation of the BNCS Full-Scale Five-Story Reinforced Concrete Building

March 2011 - December 2012

To support the BNCS project, a detailed three-dimensional nonlinear finite element model of the structure was developed and used for pre-test response simulations to predict the response of the test specimen, support the seismic test protocol design, and guide the instrumentation layout for both the structure and NCSs. This challenging research study was accomplished in three phases.

System Identification of the BNCS Full-Scale Five-Story Reinforced Concrete Building 

June 2011 - December 2012 

Using input-output and output-only structural vibration data, the modal properties of the test specimen were identified and studied both during construction and at different stages between the seismic tests. This research allowed for studying the effects of the construction process and both structural and nonstructural damage on the dynamic properties of the building system.

BNCS: Full-Scale Structural and Nonstructural Building System Performance during Earthquakes and Post-Earthquake Fire

January 2011 - October 2013 

BNCS was a landmark project involving the earthquake and post-earthquake fire testing of a five-story reinforced concrete building specimen built at full-scale and completely furnished with non-structural components and systems. ​As a core team member, I was closely involved in and contributed at all the stages of this milestone test project from its early conceptual design through the end of demolition.
