| Abstract: | Due to the load, the bend and distortion occur to the prestressed and reinforcement concrete beam bridge. By controlling the bridge pavement elevation and the designed course thickness, it can be realized by setting up an archback on the main beam bed box or lowering the elevation of pier base top. |

| Keywords: | simply supported beam set up archback elevation control |
