influence line structural analysis examples

An influence surface represents a specific component of analysis results obtained from static analyses of the traffic lane plane of a bridge structure subjected to a unit load located at the plate element nodes and is presented on the points of load application. In order to carry out a moving load analysis, we define vehicle loads, traffic lanes, or traffic surface lanes and the method of applying the vehicle loads, and then we apply a unit load at various points to traffic lanes or traffic surface lanes to calculate influence line or influence surface.Īn Influence line is presented on the traffic lane and represents a specific component of analysis results obtained from static analyses of a bridge structure subjected to a unit load moving along the traffic lane.

Moving load analysis of a bridge structure entails a series of analyses for all loading conditions created along the entire moving load path to find the maximum and minimum values, which are used as the results of the moving load case.
