ABOUT US

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.

FROM A REMOTE INDIAN VILLAGE TO  A PHD IN ENGINEERING
by Kira Vermond | University of Waterloo



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
Clearpath and Veerum, with the help of a Mitacs grant, partnered with Steve Phillips, a civil engineering graduate student from the University of Waterloo. Steve’s research is a cross between mechanical and structural engineering, focusing on using mobile robots to perform infrastructure assessment and inspection. For this project with Clearpath, he’s developed a robust, repeatable GPS Waypoint Navigation system for Clearpath’s family of outdoor robots... READ MORE
When Pampa Dey was a 10-year-old part-time cashier working in her father’s sweet shop in a remote Indian village, she discovered a love of math. With no calculator or computer to rely on, young Dey could add, subtract, multiply and divide complicated sums in her head at lightning speed.... READ MORE
