摘　　要：消能减震结构由主体结构、消能器和支撑组成的消能部件及基础等组成。其中,合适的连接构件的刚度对消能器减震效果的发挥起着关键的作用。当消能部件的连接形式比较复杂,连接构件和消能器不在同一方向时,例如各种放大装置型的连接形式,如何确定连接构件和消能器的刚度是消能减震设计的重点和难点。根据虚功原理推导出消能器和连接构件沿水平方向的变形、刚度和消能器轴向变形与层间变形关系的计算公式,对消能减震结构的设计具有重要的指导作用。The energy-dissipated structure is composed of the main body structure,the energy-dissipated component composed of the damper and support,and the foundation.Among them,the stiffness of a suitable connecting component plays a key role in the damping effect of the damper.When the connection form of the energy-dissipated component is relatively complicated,and the connecting component and the damper are not in the same direction,it is the focus and difficulty of the energy-dissipated design to determine the rigidity of the connecting component and the damper,such as the determination of the connection forms of various amplifying devices.According to the virtual work principle,the calculation formulas of the deformation,stiffness and axial relationship between the damper and the connecting components in the horizontal direction were derived,playing an important guiding role in the design of the energy-dissipated structure.
