Abstract
Abstract: Based on the pounding phenomenon at expansion joints of large-scale aqueducts during earthquakes, an analytical model that considers the effects of collision was presented, with the time history analysis method of the determining the nonlinear seismic responses, the pounding effects of adjacent girders at expansion joints on seismic responses of large-scale aqueducts were studied, and the influences on two-sided and one-sided pounding on structural responses were investigated. The results showed that the pounding changed the responding status of the aqueduct to a certain extent, the relative displacements between the girders were decreased when pounding occurred, but the huge pounding force will be harmful to the safe operation of the aqueducts. The results from the present study may serve as a reference base for seismic design of large-scale aqueducts.
