Fire Damage Identification and Valuation of Box Beam of Continuous Rigid Frame Bridge |
| |
| Abstract: | The high temperature caused by fire disaster has serious impact on reinforced concrete bridge, reducing the strength of the ordinary steel bar and pre-stressed steel bar and the concrete quality of the bridge. Combined with practical cases, the damage identification methods and evaluation meth-ods of the box beam of the pre-stressed concrete continuous rigid frame bridge after fire are introduced for reference. |
