Viscous damper with variable additional stiffness
The invention relates to the technical field of dampers, in particular to a viscous damper with variable additional stiffness. A spring set arranged in an additional rigidity cavity adopts a staged working mode to realize that additional rigidity is not provided under wind vibration and small earthquakes, so that the structural rigidity is relatively soft, the relatively large displacement amount is obtained while the earthquake reaction force is reduced, the hysteresis area of the damper is increased, and a higher additional damping ratio is obtained; by means of the principle that additional damping reinforces the structure, the additional damping ratio is increased, the steel consumption of a main body structure is reduced, the manufacturing cost is reduced, and meanwhile the higher performance target is obtained; and under medium earthquakes, major earthquakes and rare earthquakes, additional rigidity is additionally provided for the main body structure while additional damping is provided, the interlayer displacement angle of the main body structure under the action of the medium earthquakes, the major earthquakes and the rare earthquakes is controlled, and the main body structure is protected against damage from the two aspects of improving the strength and the rigidity.
本发明专利涉及阻尼器技术领域，具体涉及一种变附加刚度黏滞阻尼器；通过设置于附加刚度腔内的弹簧组采用分阶段工作的方式实现在风振和小震下不提供附加刚度使结构刚度较柔从而在减小地震反应力的同时获得相对较大的位移量，增加阻尼器的滞回面积获得更高附加阻尼比，利用附加阻尼对结构补强的原理通过提高附加阻尼比实现在减少主体结构用钢量降低造价的同时获得更高的性能目标；在中震、大震和罕遇地震下在提供附加阻尼的同时为主体结构额外再提供一个附加刚度，控制主体结构在中震、大震和罕遇地震作用下的层间位移角，从强度和刚度改善两个方面保护主体结构免遭破坏。
