N2 - A new methodology was developed that permits collection of accurate field measurements, production of as-built CAD connection drawings, and direct finite element (FE) modeling and analysis of asbuilt gusset plate connections. The method uses close-range photogrammetry techniques to rectify fieldcollected digital images taken with consumer-grade cameras to produce scaled orthographic photographs (orthophotos) of the bridge connections. From these orthophotos, the user collects true-scale measurements and exports the plate and fastener geometric information. The geometric data are used directly to create CAD drawings thereby limiting data entry errors and these as-built drawings can be compared with design drawings or used in simplified analysis and ranking methods. The same geometric data are ported to ABAQUS using scripts that generate finite element models of the gusset plates to directly assess the connection capacity.
