摘要:
For the low-rise concrete shear wall with single layer of web reinforcement, the configuration of the inclined steel bars in the web or at the bottom of wall can limit horizontal shear slip at the bottom construction joints and development of diagonal cracks on the wall, resulting in the seismic performance of wall improved. In order to investigate the influence of different arrangement of inclined steel bars on the dynamic performance and seismic damage mechanism of wall, three shaking table tests of low-rise concrete shear wall models with different reinforcement arrangements were carried out, including a wall only with single layer web reinforcement, a wall with single layer of web reinforcement and 45° inclined steel bars in the web, and a wall with single layer of web reinforcement and 45° inclined steel bars at the bottom. Based the test, the dynamic characteristics, dynamic response and failure mode of each model under elastic and elastic-plastic deformation stages were compared and analyzed. The results show that the configuration of inclined steel bars can effectively improve the seismic capacity of low-rise concrete shear wall with single layer of web reinforcement. © 2018, Editorial Office of China Civil Engineering Journal.
