Common diseases of Concrete Bridges:spalling, exposed tendons, honeycomb, concrete corrosion, mesh cracks.
2018-07-31 16:24:14Harmful cracks will not affect the bridge structure, affect the service life of bridges, accumulate over time, will lead to bridge collapse.
2018-07-30 17:35:36For cracks in concrete beams with width of 0.2-mm, besides epoxy resin pressure grouting according to the two methods, CFRP is bonded to seal the surface. Reinforced concrete beams are reinforced by CFRP sheets at the bottom of the mid span.
2018-07-30 17:13:25In order to study the effect of the external carbon fiber composite sheets on the shear strength of the specimens, the 12 specimens are rectangular beams with no abdominal reinforcement, and the bottom of the beam is matched with 2 18 longitudinal bars, and the size of the specimen is 2600 * 150 x 300.
2018-07-27 15:54:22Factors affecting the bearing capacity of beams strengthened with bonded steel plate: length of steel plate anchorage; historical loading; reinforcement ratio of steel bar; anchorage measures at the end of steel plate
2018-09-17 15:28:42The steel corrosion not only reduces the cross section of the steel, but also reduces the yield strength and the ultimate strength of the steel, which is one of the reasons for the reduction of the bearing capacity of the components.
2018-09-17 15:29:36It is possible to increase the bearing capacity of brick columns and greatly improve the lateral resistance of brick columns under the condition that the size of brick columns does not increase much.
2018-07-25 15:42:34FRP can significantly improve the shear strength of beams, but the height of FRP is different, and the bearing capacity of reinforced concrete is also different. Therefore, this adverse effect should be considered in the design.
2018-07-24 18:05:21Because the building itself is seriously damaged, we must ensure that the structure of the building is not damaged two times during construction. So at present, CFRP reinforcement is a kind of reinforcement method that minimizes the loss of buildings. It is recommended to be widely promoted in the earthquake stricken area.
