| Abstract |
The principal task of this project was to investigate whether or not it was possible to detect potentially dangerous changes in load distribution of construction framework. Laboratory measurements were taken in controlled situations, which included weak supports, loose footings, and uplifting of the supports, to ascertain the applicability of instrumented shoring at realistic construction venues. The next step was to design, fabricate and test an overall system that is capable of providing advanced and early warning capabilities to onsite construction crews working in situations where shoring accidents could happen. The end goal was to have such a sensing and alarm system be used in a large-scale construction site to verify system performance as well as provide a working environment where the alarm warning system could be fully tested and enhanced if necessary. In order to meet these lofty goals, initially a ruggedized system composed of load and tilt sensors, wireless telemetry capabilities, microprocessor based data acquisition and signal processing, and comparative software schemes was designed and fabricated. |
