［摘要］消能減震結(jié)構(gòu)由主體結(jié)構(gòu)、消能器和支撐組成的消能部件及基礎(chǔ)等組成。其中，合適的連接構(gòu)件的剛度對(duì)消能器減震效果的發(fā)揮起著關(guān)鍵的作用。當(dāng)消能部件的連接形式比較復(fù)雜，連接構(gòu)件和消能器不在同一方向時(shí)，例如各種放大裝置型的連接形式，如何確定連接構(gòu)件和消能器的剛度是消能減震設(shè)計(jì)的重點(diǎn)和難點(diǎn)。根據(jù)虛功原理推導(dǎo)出消能器和連接構(gòu)件沿水平方向的變形、剛度和消能器軸向變形與層間變形關(guān)系的計(jì)算公式，對(duì)消能減震結(jié)構(gòu)的設(shè)計(jì)具有重要的指導(dǎo)作用。

Abstract: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.

Keywords:energy-dissipated structure; energy-dissipated component; deformation of damper; stiffness of connecting component; displacement amplification factor
