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.
