摘要：
To study the shear behavior of low shear-span ration steel plate reinforced concrete shear walls, six low shear-span ration steel plate reinforced concrete shear walls were tested subjected to concentrated load. The influence of steel plate thicknesses and shear-to-span ratio on ow shear-span ration steel plate reinforced concrete shear walls were studied. The results show that all specimens failed in shear of wall web, the wall concrete formed crack zone of diagonal strut, the steel plate is yielded and the horizontal distribution of reinforcement is buckled. When the steel plate thicknesses increase from 4 mm to 8 mm, the shear strength of the wall increases by 20.4%-35.1%, although it does not affect the deformation capacity. When the shear-span ratio increases from 0.75 to 1.25, the shear strength of the wall decreases by 6.9%-18.7%, and the shear strength of the wall with thinner steel plate has a more significant decrease. The residual deformation of the wall is little influence on the thickness of steel plate. The test values indicate that JGJ 3-2010 and JGJ 138-2016 formula produce a conservative estimation of the shear strength of low shear-span ration steel plate reinforced concrete shear walls, with the estimated strength equal to 83.8% of the test values on average. © 2021, Central South University Press.
