摘要:

To study the cyclic behavior of high-strength concrete shear wall with high-strength steel bars, five shear wall specimens with a shear-to-span ratio of 2.2 were fabricated and tested subjected to constant axial load and horizontal cyclic load. The effects of the axial force ratio, the strength of distributing steel bars, the presence or absence of steel fibers, and the properties with or without wrapped steel plates on the hysteretic behavior of shear walls were analyzed. The results show that the combination of concrete with C80 grade and steel bars with HRB600 grade was a reasonable strength matching way. Increasing the strength of distributing steel bars in the wall delayed the development of cracks and reduced the residual deformation. The addition of steel fibers reduced the crack widths and improved the elastic-plastic deformation capacity. Moreover, adding wrapped steel plate at the bottom of wall effectively improved the bearing capacity, deformation capacity, and reparability of the shear wall. Finally, a restoring force model established on the basis of experiment and theoretical analysis agreed well with the test hysteresis curves.
