Abstract

Abstract

In order to study the aseismic performance of T-shaped assembled monolithic double-sided composite shear walls with constructional edge members, two full-scale T-shape shear wall specimens were tested. The test results showed that both the composite and cast-in-situ specimens displayed typical bending-shear failure characteristics in the axial compression ratio of 0.2. Compared with cast-in-situ specimens, the ultimate bearing capacity of flanges for composite specimens in the state of tension and compression was reduced by 15.7% and 3.0%; the ductility coefficient of flanges in the state of tension was the same as that of cast-in-situ specimens, while the ductility coefficient of flanges in the state of compression was lower than that of cast-in-situ specimens; the stiffness degradation laws of the two were basically the same. The cumulative energy consumption of composite specimens was significantly lower than that of cast-in-place specimens. The horizontal connection of webs, flanges and T-shaped constructional edges of composite specimens worked well as a whole. According to the test results, it was suggested to improve the stirrup ratio in constructional edge members of the composite specimens.
