【摘要】：基于基礎(chǔ)隔震理論提出框架剪力墻減震結(jié)構(gòu)優(yōu)化設(shè)計方法。針對1棟17層采用消能減震措施的框架-剪力墻結(jié)構(gòu),采用2種結(jié)構(gòu)分析軟件,選取2條實際地震波和1條人工模擬地震波分別進(jìn)行線性與非線性時程分析。研究結(jié)果表明:該方法只需將黏滯阻尼器安裝在結(jié)構(gòu)底部數(shù)層,且沒有布置抗震墻的軸線,即可取得較好的減震效果;將底部安裝阻尼器的樓層稱作隔震層,當(dāng)隔震層基本周期與特征周期相等時減震效果最好;但基本周期不能由框架與抗震墻的總剛度推算,取總剛度與安裝阻尼器的幾榀框架剛度的均值來考慮抗震墻對隔震層剛度的貢獻(xiàn),可取得理想效果;該方法合理可靠,優(yōu)化效果明顯。
[Abstract]:Based on the theory of foundation isolation, an optimal design method for frame shear wall structure is proposed. For a 17-story frame-shear wall structure with energy dissipation and damping measures, two actual seismic waves and one artificial simulated seismic wave were selected for linear and nonlinear time-history analysis using two kinds of structural analysis software. The results show that the proposed method can achieve good damping effect only by installing viscous dampers at the bottom of the structure and without the axis of the seismic wall, and the floor installed with the dampers at the bottom is called the seismic isolation layer. When the basic period of isolation layer is equal to the characteristic period, the damping effect is the best, but the basic period can not be calculated from the total stiffness of frame and seismic wall. The contribution of seismic walls to the stiffness of isolation layer can be considered by taking the mean value of total stiffness and stiffness of several frames installed with dampers into account. The method is reasonable and reliable and the optimization effect is obvious.
