Improve aseismic performance of the brick concrete structure

The aseismic performance of the brick concrete structure is generally poor, its cross wall space is too large, it is not satisfied with the requirements of the standard, the bearing capacity is insufficient, the width of the house is not satisfied, the length of the window wall is not enough, and so on.

Can CFRP be used in steel structure?

The reinforcement of CFRP does not increase the weight and size of the original structure, and the most important thing is that the reinforcement of carbon fiber cloth does not need opening and welding. It will not cause damage to the steel structure and ensure the strength and integrity of the original structure.

Slab opening reinforcement

In the transformation, the opening of the floor is normal. In the structure of the building, the floor can bear the vertical load on the upper part, and provide the lateral stiffness for the structure, coordinate the lateral deformation of the structure, and maintain the role of the whole work together.
