【摘要】：為研究高烈度區(qū)框架結(jié)構(gòu)裝設(shè)非線性黏滯阻尼器減震效果,以某典型框架結(jié)構(gòu)工程實例為背景,輸入地震波進行時程分析。以樓層側(cè)移、層間位移角、樓層剪力為減震控制目標(biāo),分析結(jié)果表明,裝設(shè)黏滯阻尼器的結(jié)構(gòu)減震效果明顯,阻尼器在不同的工況下滯回曲線均勻飽滿,呈現(xiàn)典型的非線性速度型阻尼器特征,分析結(jié)果對于黏滯阻尼器在高烈度區(qū)的應(yīng)用與推廣具有一定的參考價值。
[Abstract]:In order to study the effect of nonlinear viscous dampers on the seismic response of frame structures in high intensity region, a typical frame structure engineering example is taken as the background, and the seismic wave is input for time-history analysis. Taking the lateral shift of the floor, the displacement angle of the floor and the shear force of the floor as the control targets, the results show that the damping effect of the structure with viscous damper is obvious, and the hysteresis curve of the damper is uniform and full under different working conditions. The analysis results are useful for the application and popularization of viscous dampers in high intensity regions.
