ABOUT US RESEARCH
Our research has two main theme areas. First, we are working on identification and control of dynamically sensitive structures which are vulnerable to natural (wind, earthquake) and man-made (e.g., machinery, pedestrian) dynamic forces. We are primarily interested in understanding the behaviour and condition of structures through sensor measurements, and to develop innovative means to control unwanted responses in dynamically sensitive structures. We are working on developing powerful system identification and parameter estimation algorithms using concepts of blind source separation, Kalman filtering, unsupervised classification, and time-frequency analysis. We have significant ongoing research on lightweight footbridges such as aluminum, where we are studying the dynamic effects of pedestrian loading and the deployment of autonomous vibration control systems.

The second theme area is in condition monitoring of civil and mechanical systems such as rotating mechanical equipment, bridges and water distribution networks. We are primarily interested in vibration and acoustic-based sensors to undertake condition assessment. We are working on signal processing, machine learning and reliability methods to develop novel detection, degradation and maintenance models to assist with maintenance and operations. Autonomous aerial vehicles are being assessed for their use in inspecting steel and concrete bridges to augment current inspection techniques where access is difficult.

In this webpage, you will find a summary of our key research themes, publications and information about our current team members.

OVERCOMING OBSTACLES TO ACHIEVE HER DREAMS

Sriram Narasimhan’s research team is shaking things up in the Civil Engineering Structures Lab at the University of Waterloo. The research, which is led by Ph.D Candidate Kevin Goorts, is developing a new mobile damping system for suppressing unwanted vibrations in lightweight, flexible bridges. Whereas damping systems are often permanent fixtures built into the bridge, their system... READ MORE
It was the costliest disaster in Canadian history, but for Fort McMurray residents trapped on clogged evacuation roads while the May 3, 2016 wildfire raged nearby, it was also something else: terrifying. According to engineer Sriram Narasimhan, however, coming technology in sensors and data analytics could soon make community evacuations in such crises safer and more orderly... READ MORE
As a young girl, Pampa Dey lived with her parents and two siblings in a small one-room house in the remote village of Ranibandh, India where a kerosene lamp was often the only source of light. Starting at the tender age of 10, she worked as a part-time cashier in her father’s small sweet shop to help support her family... READ MORE
