Problems solved by technology

The development of prefabricated structural systems is the only way for building industrialization, but the existing prefabricated structures used in high-intensity areas have disadvantages such as poor node reliability, poor structural integrity, large residual deformation of the structure, and insufficient energy dissipation capacity and ductility of the structure. It is often difficult to meet the stress requirements under repeated loads, and the use in high-intensity areas is limited

At present, although a large number of scholars have proposed beam-column joints, the joints are close to the core area of ​​beam-column joints, and the reinforced steel bars are densely reinforced in the joint area, which makes the joint force very complicated and the construction is difficult and uneconomical, especially under the action of earthquakes. It is difficult to achieve "strong columns and weak beams" and "strong joints and weak members". It is difficult to repair after the earthquake, causing a lot of economic losses to people
