Static Load Test and Modal Analysis of Qingshui River Bridge

Abstract:

A load test on a multi-girder concrete bridge of 30m Span having a non-composite deck slab is described. The bridge was designed to have eight simple supported spans, each consisting of a cross section with six RC T beam. Through analyzing the static and dynamic character of bridge structures, calculating efficiency ratio of load test, picking up the results of observation points, it was determined that the girders were acting non-compositely with the concrete deck and that significant restraint was being developed at the bearing supports. Modal analysis and identification ascertain the characteristic properties of bridges from their response. The damage in bridges may be reflected in the changes of their natural frequencies or modes of natural vibration.
