Device and method for simulating typical damage of cable-stayed bridge

The invention discloses a device and a method for simulating typical damage of a cable-stayed bridge. The device for simulating typical damage of the cable-stayed bridge comprises five subsystems, namely a main beam system, an inhaul cable system, a pier tower system, a load system and a measuring system. The main beam system is used for simulating the typical damage working condition of a main beam of the cable-stayed bridge; the inhaul cable system is used for simulating a typical stay cable breaking damage working condition; the pier tower system is used for fixing the main beam system andthe inhaul cable system; the load system is used for providing different static load working conditions; and the measuring system is used for measuring the cable force of the inhaul cable system, theinternal force of a main beam in the main beam system and the rigidity of the main beam in the main beam system. The method can effectively obtain the performance degradation rule of the cable-stayedbridge under typical damage
