Pseudo-Static Experiment Study on Recycled Concrete High Shear Walls

Article Preview

Abstract:

The low-cyclic loading tests are carried out for three pieces of recycled concrete high shear walls, with 100% replacement ratio of recycled coarse aggregate under different axial-load ratios. The mechanical performances of shear walls, including failure patterns, the bearing capacity, the hysteretic properties and ductility, are analyzed. The test results indicate that the basic behavior of recycled concrete shear walls resembles quite closely that of the ordinary concrete shear walls, the recycled concrete shear wall under bending failure has good ductility and bearing capacity; the hysteresis loop is stable and the degradation of stiffness is not great; the shear-slip phenomenon becomes significant and the ductility decreases under high axial-load ratio. The calculation of flexural strength of recycled concrete shear walls can be adopted directly from computational theories and formula used for ordinary concrete shear walls. It is feasible to apply reasonably designed recycled concrete shear walls to small high-rise buildings.
