Establishing Connection Methods for Precast Concrete Shear Wall

Following rapid economic development, many countries have realized the necessity for the development of prefabricated construction. Therefore, it is predicted that the development of prefabricated concrete structure has become an increasingly important domain. In practical applications, the connection construction of precast components is complex, which is reflected in the need to pour concrete or grouting at the joint. Owning to that, the prefabricated concrete structure still belongs to the assembly monolithic structure to a large extent. Low assembly rate and high cost, both factors found to limit the prefabricated concrete structure, are important factors in widespread promotion. In addition, the prefabricated concrete shear wall structure is an important part of the prefabricated concrete structure, with good structural integrity and high rigidity at the joint region. However, for fabricated concrete shear wall structures, the wall structure is usually prefabricated in the factory, which not only resulted in transportation problems, and also difficulties pertaining to the construction standardization. Without doubt, it is imperative to study the prefabricated concrete structure with lower cost, simpler structure, convenient connection and good comprehensive performance, so as to promote the development of residential industrialization. Undoubtedly, reinforcement connection technology is one of the key technologies of prefabricated concrete structure. The joint is often the weakest link of the whole structure. The reliable connection between the prefabricated components can effectively guarantee the integrity and seismic performance of the structure. This paper shed some light on the precast concrete shear wall common connection methods.
