Cracks in reinforced concrete(RC) structural members

Structural cracks not only represent the structural stress, but also affect the durability of structures. The bigger the crack width is, the easier the steel will corrode, which means that the bond between the steel bar and the concrete has been completely destroyed and the service life has come to an end.

Bonded steel plate reinforcement method

In construction, the steel plate will be attached to the outer edge of the stressed part of the reinforced structure with structural steel plate bonding adhesvie​, in order to give full play to the strength and effect of the steel plate, and to close the cracks in the pasted parts at the same time, to restrain the deformation of the concrete, and thus effectively improve the crack resistance and stiffness of the reinforced component.

Seismic reinforcement of concrete structures

If the bearing capacity of the building structure can meet the requirements, it is preferable to adopt the method of changing the structural system instead of reinforcing its components. When reinforced concrete structural members are required strengthening, the reinforcement method adopted in the design shall comply with the following table rules.

The application of carbon fiber fabric for strengthening

Carbon fiber fabric or structural strengthening, repairing and retrofitting of masonry, concrete, steel and wooden substrates.FRP composite strengthening of columns,beams,slabs,walls,piles,pier caps in building,bridge,highway,railway,tunnels,piers and civil airport.

Carbon fiber fabric for concrete structure strengthening

For general structure, carbon fiber fabric or precured carbon fiber plate can be selected according to the actual situation of the project. For long-span structures, heavy structures and other important structures, precured carbon fiber plate should be preferred and reinforcement measures should be taken.
