Abstract: Prestress applied on bridges affects the dynamic interaction between bridges and vehicles traveling over them. In this paper, the prestressed bridge is modeled as a beam subjected to eccentric prestress force at the two ...

Abstract: How to detect the prestress loss of the bridge in a fast and economical way is still a challenging problem for bridge engineers. Although some sensors have been developed to monitor the prestress, it is usually difficult ...

Abstract: An abnormal phenomenon may occur during gaswell testing: the wellhead pressure initially rises and then drops when shuttingin a well; the wellhead pressure initially drops and then rises when opening a well. To determine ...
