| Abstract: | There are deficiencies in the optimization of the seismic performance of high-rise building shear walls, such as weak integrity and collapse resistance. Aiming at this problem, this study innovatively combines the partial replacement of concrete and steel pipe reinforcement technology, and proposes a method of locally adding steel pipe reinforcement shear walls. The experimental results showed that the specimens reinforced by the studied method exhibited better ductility and toughness when subjected to a vertical load of 840.84 kN as compared to the lowstrength concrete specimens that were not reinforced by the studied method. The overall structure of the wall was able to maintain its load-bearing capacity despite the fact that the concrete at its base also suffered from crushing and spalling. In addition, the cracking displacement of the specimens (JGC-2, JGC-4, JGC-6) with localized steel pipe reinforcement was only 3.0 mm, 2.1 mm, 2.4 mm, respectively. The limit displacement was only 27.0 mm, 24.0 mm, 25.0 mm, and 45.0 mm, 47.0 mm, and 36.0 mm, respectively. The destructive displacement was only 45.0 mm, 47.0 mm, and 36.0 mm. The superiority of partial replacement of concrete and steel pipe reinforcement in improving the performance of high-rise building shear wall structures was further confirmed. It can be concluded that the research method can not only provide new ideas for the seismic strengthening of existing high-rise buildings, but also is expected to play an important role in a wider range of engineering applications. In turn, this will contribute to the improvement of the seismic performance of high-rise building structures and the protection of people's lives and property safety. [ABSTRACT FROM AUTHOR] |
