چکیده
Abstract: Shear deformation is the most principal deformation in the lateral deformation of shear wall built with precast hollow slab which is designed to be strong shearing and weak bending. The special mechanical characteristic of the shear wall is the relative deformation of the concrete on both sides of vertical and inner joint respectively. The study introduces the measuring scheme of shear wall deformation and steel strain. The measuring method of shear deformation is designed and the device is used to measure horizontal and vertical relative deformation of the concrete near joints. It has been proved that the experimental measuring scheme can monitor the shear wall deformation and the steel strain successfully. The measuring methods of shear wall deformation and relative deformation are reasonable and feasible.

Experimental Study on Precast Concrete Shear Walls with Different Hollow Slabs
To study mechanical behaviors of shear walls built with precast two-way hollow slabs, two shear walls with different details of hollow slabs were quasi-statically tested under low cyclic loading. The failure mode was analyzed, which vertical macro-cracks appeared on walls due to the details of hollow slabs. Brittle shear failure can be avoided in terms of the failure behaviors evolved from inte...

Result and Conclusion: 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...
