Abstract

As part of the National Cooperative Highway Research Project 12-84 "Guidelines for the Load and Resistance Factor Design and Rating of Gusset-Plate Connections for Steel Bridges" the Federal High-way Administration (FHWA) is performing large-scale gusset-plate experiments. The National Institute of Standards and Technology is working in conjunction with FHWA to perform digital image correlation (DIC) measurements during these experiments. This work focuses on a portion of the DIC measurements for one plate configuration, and presents a preliminary comparison of these data to other measurement methods being used including 3D laser position tracking, foil strain gauges, and photoelastic strain mapping. The results show qualitative agreement between full-field results of the methods in regards to measuring the initial shape and elastic strains. Additionally, a more quantitative comparison shows general agreement between the metrologies within the uncertainties of the methods.
