带V型减震器的框架──核心筒体结构动力计算方法

Dynamic Calculating Method of Frame-Core Tube Structures Equipped With V-shaped Energy Absorbers

高层框架——核心筒体结构中，在框架与核心筒体连接处设置V型减震器，使框架与核心筒体之间的刚性连接变成了弹性阻尼连接，从而减小了地震作用下结构的动力反应。本文通过对带V型减震器的高层框架——核心筒体结构动力特点的分析，建立了这种减震结构的动力计算模型，提出了这种减震结构的动力计算方法，并对计算公式进行了推导。

V-shaped energy absorbers are installed in the connection part of frame andcore tube in tall frame-core tube structures. This transforms stiff connection of frame andcore tube into elastic damping connection,thus,reduces dynamic response to the structuresin earthquakes. Through the analysis to dynamic characteristics of tall frame - core turestructures equipped with V - shaped energy absorbers, this paper establishes, dynamiccalculating model,presents dynamic calculating method, and derives calculating equationof the structures.
