Problems solved by technology

[0002] The traditional prefabricated integral shear wall structure has the following defects: first, it consumes a large amount of concrete, which requires a lot of mountain quarrying and digging sand, which seriously damages the ecological environment; second, the materials used are single and the reliability of node connections is poor. The structural integrity is poor, and the structural system lacks multi-channel fortification anti-seismic mechanism, which makes it difficult to meet the stress requirements under repeated loads; third, the structure cannot achieve ductility design by developing uniformly dispersed energy-dissipating cracks, resulting in waste and unreasonable use of materials
