Response of Pin-Connected Truss Bridges to Wind
Preservation of historic bridges has led to renewed interest in understanding the response of pin-connected truss bridges to lateral loads. While numerous examples of full-scale gravity load testing on truss bridges can be found in the literature lateral load tests on truss bridges of ordinary span lengths are another matter. A low-cost instrumentation system was developed to obtain data from lateral loads on pin-connected truss bridges. The results provide insight into actual performance of pin-connected truss bridges under lateral loads. Both the stiffening effect of different deck types and the actual flexural response of portal frames are examined. The actual responses are compared to results from analyses. These findings are offered as a first step toward experimental investigations of lateral load response on ordinary truss bridges, the type of bridges now of interest for historic preservation. The testing was conducted as verification for a new application of structural modeling for historic truss bridges. The goal of this project was to aid preservation efforts for one of the cradles of civil engineering heritage: the pin-connected truss bridge.
