Abstract: Recently, Buchanan County, Iowa, cooperated with the U.S. Federal Highway Administration (FHWA), USDA Forest Service, Forest Products Laboratory (FPL), and Iowa State University’s Bridge Engineering Center (ISU–BEC) and the National Center for Wood Transportation Structures (NCWTS) on a project involving the construction and monitoring of a gluedlaminated (glulam) timber bridge superstructure on geosynthetic reinforced soil (GRS) integrated bridge system (IBS) abutments. The research team installed sensors within the substructure, at the girder bearings, and on the superstructure. Together, the system creats an autonomous structural health monitoring system that remotely transmits continuous data. Long-term monitoring enables researchers to evaluate GRS–IBS system performance with respect to variables of time, ambient conditions, and loading.
