Experimental Study on Shear Performance of Innovated Precast Shear Walls with Different Yield Strength Grades of Reinforcements

The hollow slab shear wall structure is a new type of shear wall structure by industrial production.

To study the mechanical performance of the new-typed walls with different horizontal bars strength, quasi-static tests were carried out for two hollow slab shear walls.

The results show that strength of horizontal bars has a little influence on the hysteretic behavior and the deformation ability. While the decrease of the strength of horizontal bars can increase the yield displacement and the peak displacement of the hollow slab shear walls. The hollow slab shear wall structure has good deformation capacity, and the brittle shear failure can be avoided.
