Abstract：In two groups with sectional longitudinal reinforcement ratios of 1.7% and 2.5% respectively, eleven specimens of shear wall with shear-span ratio of 1.5 and with different axial tensions were tested for their tension-shear performances. Under the combined actions of tensile force and shear force and depending on the relative magnitude of the two forces, shear walls may be in the tension state of large eccentricity or in the tension state of small eccentricity, which leads to the shear-compression failure mode or the slip failure mode, respectively. The test results show that the influences of axial tension and sectional longitudinal reinforcement ratio on the shear capacity, lateral stiffness and cumulative hysteretic energy of shear wall were opposite. That is, these performances may be decreased with the increase of tensile force, and be increased with the increase of sectional longitudinal reinforcement ratio. Compared with the compression-shear failure, the ultimate deformation capacity and the ductility of shear wall may be increased under the tension-shear action. The deformation capacity of shear wall may be increased with the increase of sectional longitudinal reinforcement ratio. The equivalent viscous damping coefficient of shear wall may be increased with the increase of tensile force, and be decreased with the increase of sectional longitudinal reinforcement ratio.
