Tooth-grooved connection is a new type connection mode for prefabricated shear wall. Compared with the current connection mode, the Tooth-grooved connection is more convenient and lower cost. According to the result of early experimental study and numerical analysis, which is conducted by the applicant, it shows that the failure pattern, seismic ductility and bearing capacity of the precast wall specimens are similar to the cast-in-place wall specimens under quasi static loading. Currently, prefabricated shear wall bearing capacity calculation methods with domestic specifications are mainly matching the grout sleeve splicing. Further research is necessary for prefabricated shear wall with Tooth-grooved connection node to meet practical requirements, and it could involving engineering economics and structural reliability.The applicant is planning to conduct a method which combined theoretical analysis, numerical simulation and experimental investigations, to make a systematic study for the influence factors of shear bearing capacity, such as interfacial bonds and friction characteristics between the new and old concretes, dowel action of vertical distribution-bar and cumulated damage of concrete. Development of plastic zones and formation mechanism of compression strut in alveolar area will be studied, and relationship between various factors will be analyzed through truss model. The research will be conducted for the influence of lap length of vertical distributed reinforcements in the alveolar area on the bond-slip properties, as well as the influence on flexural capacity of connection and section ductility. Systematic formulas of bearing capacity will be established and key seismic design parameters will be identified to improve the theoretical foundation of prefabricated structures.
