针对抗侧刚度较弱的装配式结构纵向框架研究较少的现状,建立了纯框架、增设防屈曲支撑及增设阻尼器的装配式框架有限元分析模型,通过非线性的时程对比分析了在地震作用下三种模型纵向体系的结构反应。分析表明,在类似结构中增设阻尼器,可显著提高减震效果,使结构在大震中依然处于弹性状态。对于进一步提高阻尼器在纵向框架的应用水平具有一定的借鉴意义。
針對抗側剛度較弱的裝配式結構縱嚮框架研究較少的現狀,建立瞭純框架、增設防屈麯支撐及增設阻尼器的裝配式框架有限元分析模型,通過非線性的時程對比分析瞭在地震作用下三種模型縱嚮體繫的結構反應。分析錶明,在類似結構中增設阻尼器,可顯著提高減震效果,使結構在大震中依然處于彈性狀態。對于進一步提高阻尼器在縱嚮框架的應用水平具有一定的藉鑒意義。

For the lack of researches of the longitudinal framing of fabricated structure with weak lateral stiffness, non-damped, buckling-restrainedbrace and damped structure finite element analysis models were es-tablished .The three models'earthquake reaction in the longitudinal system were compared by the nonlinear time history analysis method .Analysis shows that the similar structure with damper can significantly improve the damping effect , and keep the structure in the elastic stage under the major earthquake .The paper can provide a reference for damper's application in the longitudinal framing .
