ULTIMATE LOAD BEHAVIOR OF FULL-SCALE HIGHWAY TRUSS BRIDGE: PHASE II - SERVICE LOAD AND SUPPLEMENTARY TESTS

As a result of the construction of Saylorville Dam and Reservoir on the Des Moines River, Six highway bridges crossing the river were scheduled for removal. Two of these were incorporated into comprehensive test program to study the behavior of old pin-connected high-truss single-lane bridges. The test program consisted of ultimate load tests, service load tests and a supplementary test program. The results reported in this report cover the service load tests on the two bridges as well as the supplementary tests, both static and fatigue, of eyebar members removed from the two bridges. The field test results of the service loading are compared with theoretical results of the truss analysis. /FHWA/
