【摘要】：研究一種搖擺式鋼筋混凝土框架節(jié)點剛度的取值方法。首先,建立了搖擺式鋼筋混凝土框架的有限元模型并進行了地震模擬振動臺試驗驗證;其次,選擇10條地震動曲線,研究9種不同節(jié)點相對剛度比情況下結(jié)構(gòu)的動力時程響應分析;最后,利用層間位移放大系數(shù)、基底減震系數(shù)比較不同地震動作用下結(jié)構(gòu)的峰值層間位移、層間剪力響應。結(jié)果表明:節(jié)點相對剛度比S取0.01~0.25為宜。
[Abstract]:A method for determining the stiffness of swing reinforced concrete frame joints is studied. Firstly, the finite element model of swinging reinforced concrete frame is established and verified by shaking table test. Secondly, 10 ground motion curves are selected to study the dynamic time history response analysis of structures under 9 different relative stiffness ratios of joints. Finally, the peak interstory displacement and interstory shear response of structures under different ground motion are compared by using the magnification factor of interstory displacement and the damping coefficient of basement. The results show that the relative stiffness ratio S of the joint is 0.01 鈮，
