Development of a strain transducer device for use on structural steel members was developed. The inexpensive, reusable transducer can be conveniently and nondestructively clamped to a structural member. It can be reused. Prototype devices have been tested in the laboratory to verify reliability and repeatability of results and have been compared to analytical results. The device has been successfully used in the field on full-scale members. Each device cost approximately $50 USD. Experimental strain measurement of a weathered structural member using strain gauges usually involves the surface preparation work of grinding to remove paint and corrosion, sanding to create a smooth uniform surface, member polishing, bonding, and clamping of the strain gage. This is in addition to other miscellaneous field installation preparation tasks. Access can sometimes be hazardous and the task is always inconvenient. The device presented in this paper has been developed through a combination of laboratory research and finite element modeling.
