Increase the section reinforcement of members, the connection between connecting bars and connecting bars, crack repair and reinforcement.

The steel structure can be strengthened by increasing the cross section of the component. When strengthening, the shortcomings and damage of the structure should be considered, and the correct measures should be taken. The connection between the reinforcement and the reinforcement can be welded or riveted. The reinforcement should be arranged according to the structure. When cracks appear on the surface of the rigid structure, the repair and reinforcement should be carried out in a timely manner. Before the repair, the causes of the cracks must be seen clearly, and then the repaired and reinforced components should be used for reinforcement.

What are the steel structure reinforcement technologies?

The section reinforcement method is to strengthen the members locally or along the whole length with steel bars and connect them into a whole, so that they can bear the force together, change the calculation diagram to add additional supports, adjust the load distribution, reduce the internal force level, force the displacement to exceed the static structural support, and reduce the peak stress. The prestressed cable method is to use high-strength cables to strengthen the weak links of the structure or improve the overall bearing capacity, stiffness and stability of the structure.

What to choose for steel structure reinforcement

Welded joints and friction type high-strength bolts shall be selected for steel structure reinforcement. When there is a foundation, mixed joints of welded joints and friction type high-strength bolts can also be selected. When welding joints are selected for connection, welding processes and connecting materials approved by the assessment shall be selected. When cracks with expansive or brittle fracture tendency occur due to repeated load and improper material selection, construction, manufacturing, construction and installation, they shall be corrected.
