Construction site of seismic isolation bearings of Hebei Shangze Yining Hospital
Introduction to Yining People’s Hospital
Yining People’s HospitalFounded in 1958, it is located at No. 66 Xinhua East Road. It is adjacent to the national 4A-level famous scenic spot Kazanqi Folk Tourism Area. After generations of unremitting efforts of medical workers, it has developed into a Class-A Class-II comprehensive hospital integrating medical treatment, scientific research, teaching, emergency treatment, prevention and health care. It has 500 beds and 763 employees, including 698 professional and technical personnel, 88 senior titles, and 610 junior and middle-level titles. It has 17 clinical departments including endocrinology and hypertension, digestive and respiratory neurology, cardiology and nephrology, psychosomatic medicine, obstetrics and gynecology, pediatrics, orthopedics, general surgery, and 7 medical and technical departments including laboratory, functional and imaging.
Why install seismic isolation bearings?
The reason why buildings are installed with seismic isolation bearings can be summed up in one sentence: to protect the safety of buildings and the people in them to the greatest extent when an earthquake strikes.
Specifically, the role of seismic isolation bearings is mainly reflected in the following aspects:
- Isolation of seismic energy:
Traditional buildings firmly fix the foundation and the main structure together. When an earthquake occurs, the powerful energy will be transmitted to the building without reservation, causing structural damage or even collapse.
The seismic isolation bearing is like a “spring” or “slide plate” installed between the building and the foundation. During an earthquake, it can effectively isolate or dissipate the energy transmitted from the seismic waves to the superstructure, reducing the impact of the seismic force on the building, thereby protecting the safety of the main structure of the building.
- Extending the natural cycle of buildings:
Each building has its own inherent vibration cycle, and earthquake waves also have their own vibration cycle. When the two cycles are close, resonance will occur, causing great damage to the building.
Seismic isolation bearings can extend the natural period of a building, keep it away from the predominant period of seismic waves, avoid the occurrence of resonance, and thus reduce the damage caused by earthquakes to the building.
- Reduced seismic response:
Seismic isolation bearings can effectively reduce the seismic response of buildings such as acceleration, floor displacement and inter-story displacement angle under earthquake action, improve the seismic performance of buildings and reduce the losses caused by earthquakes.
all in all, The seismic isolation bearing is like a layer of “protective clothing” for the building. When an earthquake occurs, it can minimize the impact of the earthquake on the building and protect the safety of the building and the people inside it.
Of course, the selection and installation of seismic isolation bearings require professional technicians to design and construct them in order to achieve their maximum effectiveness.
