Description

Single-hole steel plate energy dissipator

technical field

The utility model relates to a building structure vibration control device, in particular to a single-hole steel plate energy dissipator.

Background technique

Because metal materials have good hysteresis properties after entering plasticity, they are used to make various types of energy-consuming devices. The steel plate energy dissipator device is generally a passive energy dissipation shock-absorbing device assembled from low yield point or extremely low yield point steel plates and its positioning device. The anti-seismic mechanism is simple, the cost is low, and the effect is remarkable. At the same time, the device is generally installed in the structure as a non-load-bearing component. Under normal use conditions, it can increase the overall stiffness of the structure; Relatively small, the steel plate energy dissipator does not enter or a small part enters the plastic stage; when encountering a large earthquake or a rare earthquake, the energy dissipator should first enter the plastic stage, relying on the plastic energy generated by it to reduce the seismic response of the structure , its destruction will not affect the use of the overall structure. The device can be used not only for the aseismic design of new engineering structures but also for the reinforcement and maintenance of existing buildings, and has good economic benefits.
