The static test of the low-cycle repeated action on the curtain wall specimen is used to simulate the force and deformation process of the curtain wall under the repeated level of the ground when subjected to earthquake or wind load.

 

 

 

     2, interlayer displacement

 

 

 

     Relative horizontal displacement between two adjacent floors of a building under the action of earthquakes and wind.

 

 

 

     3, the displacement angle between layers

 

 

 

     The ratio of the interlayer displacement value to the layer height.
