Abstract

Abstract

In order to study the seismic performance of joints and integral components of T-shaped prefabricated shear walls with enengy-dissipating vertical joints, quasi-static tests were carried out on two T-shaped shear wall specimens with enengy-dissipating vertical joints until the specimens were damaged. The damaged specimens were reinforced with carbon fiber sheets and subjected to secondary loading. The main change parameter of the shear wall was the axial compression ratio (0.1, 0.3). The bearing capacity, hysteretic performance, energy dissipation performance and stiffness degradation of the shear walls before and after reinforcement were compared and analyzed. The research results showed that:T-shaped shear wall with enengy-dissipating vertical joint showed good working performance, and the CFRP reinforced structure could quickly restore the building's function. The displacement ductility coefficients before and after reinforcement were close to or higher than 3, which reflected the good deformability of the specimen. The damper had good connection and working performance, and the specimen as a whole showed good enengy-dissipating capacity.
