摘要:
The inclined reinforcements are configured in low-rise reinforced concrete shear wall with single row of steel bars and low reinforcement ratio, which can limit horizontal shear slip at the bottom construction joints and development of diagonal cracks on the wall. To investigate optimization design method of reinforcements for low-rise concrete shear wall with single row of steel bars and inclined reinforcements, the cyclic loading tests of 5 shear walls with different reinforcement design were carried out. The failure characteristic, hysteretic property, load-carrying and deformation capacity, stiffness degradation, energy dissipation and reinforcement strain were compared and analyzed. The results show that the seismic performance of shear wall with inclined reinforcements is better than the wall without inclined reinforcements, because the inclined reinforcements can control the shear deformation effectively. If inclined reinforcements are reasonably allocated, energy dissipation capacity of low-rise concrete shear wall can be significantly improved and higher performance price ratio of structural wall can be obtained. © 2017, Editorial Board of Journal of Harbin Institute of Technology.
