Real-Time System for Stand-Off Measurement of Structural Stability

This project will utilize a non-contract ultrasonic sensing system previously developed by Summit Safety, and convert it from an engineering tool to a user-friendly system capable of providing real-time measurement of structural stability and advanced warning of pending collapse. The sensor is capable of measuring very small changes in position (less than a ten-thousandth of an inch) from a standoff distance of over ten feet. The sensor also provides high-resolution measurements of velocity and acceleration. The system incorporates multiple sensors connected by wireless link to a central display unit. Unlike laser-based systems, the ultrasonic system is capable of operating in dense smoke. Phase 1 will focus on the issue of how to best use the system for collapse detection and prediction in different collapse scenarios with specific types of structures utilizing specific construction materials. Phase 1 will also determine the types of information and the preferred manner for displaying that information for the first responders and emergency personnel who operate at a potential collapse site.
