Testing system for action of uneven settlement of foundation and horizontal load on structure

The invention provides a testing system for action of uneven settlement of a foundation and a horizontal load on a structure. Multiple supports are erected between the bottom of a fixing steel beam and the ground. The fixing steel beam is fixedly connected with the ground through threaded rods. A support is erected between one end of the bottom of a loading steel beam and the ground, and the loading steel beam is fixedly connected with the ground through threaded rods. A jack is arranged between the other end of the bottom of the loading steel beam and the ground, and a longitudinal through hole is formed at the other end of the bottom of the loading steel beam. The lower end of a pressure threaded rod penetrating through the longitudinal through hole is fixed to the ground. The upper endof the pressure threaded rod is sleeved with a locking nut. Four support seats at the lower end of a structure model are fixedly connected with the fixing steel beam and the loading steel beam pairwise correspondingly. The up
