Safety Evaluation of Pier under Impact of Bridge Girder Erection Machine

Abstract:

A tie beam in a pier is demaged owing to the collapse of the bridge girder erection machine in the construction. In order to evaluate the safety of the pier stud, the effect of force induced by the impact of the collapse is analyzed. The results show that the concrete in bottom of the pier is compressed and that the tensile stress of concrete in the root of the damaged tie beam is less that the designed tensile strength of the concrte. The analyzed results are in line with the real state of the damaged tie beam.
