Load test of tied arch with concrete filled steel tubular in the urban area

The load test of a tied arch bridge with concrete filled steel tubular is studied in the paper. The difference of tied arch bridge and the conventional arch bridge is discussed on the basis of its theoretical analysis, then the test section, arrangement of the measuring points and the testing of suspender force are investigated, finally, the experiment results are compared with those of theoretical analysis, which show that the bearing capacity of the bridge can meet the service demands, and the bridge is under a good working conditions. The presented method and its achievements can give reference to the engineers.
