［摘要］對一座形狀不規(guī)則的、縱向剛度遞減的框架-剪力墻結(jié)構(gòu)采用黏滯阻尼墻和軟鋼阻尼墻兩種減震方案進行減震效果對比分析。對未減震結(jié)構(gòu)、設(shè)置黏滯阻尼墻減震結(jié)構(gòu)和軟鋼阻尼墻減震結(jié)構(gòu)進行7條地震波激勵下的動力響應(yīng)對比分析，結(jié)果表明，兩種減震方案均能有效降低結(jié)構(gòu)位移響應(yīng)，位移減震效果兩者均達到40%，樓層層間剪力結(jié)果表明設(shè)置黏滯阻尼墻減震效果達到35.68%，而軟鋼阻尼墻的層間剪力與未減震結(jié)構(gòu)結(jié)果一致。以上結(jié)果說明框架-剪力墻結(jié)構(gòu)盡管樓層位移較小，但黏滯阻尼墻由速度耗能給結(jié)構(gòu)附加較多阻尼而減小地震力。軟鋼阻尼墻為位移型，由于樓層層間位移較小無法提供較大的耗能能力從而未能達到較好減震效果。

Abstract: A comparative analysis of damping effect of a frame-shear wall structure installing viscous damping wall and mild steel damping wall was studied. The frame-shear wall structure was irregular and stiffness decreasing with height in the vertical direction. Seven seismic wave excitations were input to no damping structure, viscous damping wall structure and mild steel damping wall structure to get the comparative analysis of their dynamic response. The results show that both damping scheme can decrease the drift response and both of the drift damping effect can reach 40 percent. The story shear force damping effect of viscous damping wall structure can reach 35.68 percent, while the result of mild steel damping wall structure is almost the same with no damping structure. The results above show that although the displacement of the frame-shear wall structure is small, but the viscous damping wall structure with speed energy consumption can decrease the story shear force through adding more damping to the structure. Mild steel damping wall structure with displacement energy consumption can not reach good damping effect because small story displacement can not provide large energy dissipation capacity.
