Experimental system for out-of-plane seismic performance of masonry block wall, and experimental method using same

A seismic performance testing system for a masonry wall plane, comprising:

• a static base,
• a transverse limiting system set on one side of the static base,
• a lateral load system set on an other side of the static base, and
• a test masonry wall set between the transverse limiting system and the lateral load system;
• wherein
• the test masonry wall is fixed to the static base by a foundation beam, and a circular beam is poured above the test masonry wall;
• the testing system further comprises a vertical load system set above the circular beam;
• the transverse limiting system comprises at least one tripod set on one side of the test masonry wall;
• a base of the tripod is fixed to the static base, and multiple first screws are set between an upper end of a tripod plane and the circular beam;
• a lower end of the tripod plane is fixedly connected to the foundation beam;
• an oblique side of the tripod is also equipped with a pad, which is fixed on the static base;
• a horizontal jack is set between the pad and the oblique side of the tripod;
• the lateral load system comprises a reaction wall fixed to the static base and set on the other side of the test masonry wall;
• a horizontal reciprocating actuator is set between the reaction wall and the test masonry wall, and a multi-level shear distribution device is set between the horizontal reciprocating actuator and the test masonry wall;
• the multi-level shear distribution device comprises a long H-shaped steel member and two short H-shaped steel members;
• one side of the long H-shaped steel member is movably connected to the end of the horizontal reciprocating actuator, and an other side of the long H-shaped steel member is symmetrically set with short H-shaped steel members at the upper and lower ends;
• the long H-shaped steel member and the short H-shaped steel members are fixedly connected by a steel pipe;
• the two short H-shaped steel members are connected to a double-sided screw connection device fixed on the test masonry wall;
• the vertical load system comprises at least one reaction frame, which comprises a horizontal beam fixed to the static base by a column and placed above the circular beam;
• a compression beam is connected below the horizontal beam, which is flush with the circular beam and placed directly above it;
• and multiple vertical jacks are set between the compression beam and the circular beam.
