【摘要】：借助ANSYS軟件分別模擬單擺和三擺隔震支座,通過提取滯回曲線得出三擺隔震支座的特點;然后根據(jù)非對稱框架結(jié)構(gòu)的自身特點,通過采用數(shù)值模擬對非對稱結(jié)構(gòu)設(shè)置三重摩擦擺新型隔震支座對在8度罕遇地震作用下的響應(yīng),根據(jù)上部荷載不同設(shè)置不同參數(shù)的三重摩擦擺隔震層,對其隔震效果進(jìn)行分析比較。計算結(jié)果顯示,采用三重摩擦擺隔震可使上部結(jié)構(gòu)的地震反應(yīng)顯著減小。通過合理設(shè)置三重摩擦擺的關(guān)鍵參數(shù),對隔震層和上部結(jié)構(gòu)的位移進(jìn)行調(diào)整,可實現(xiàn)對隔震層的水平位移、扭轉(zhuǎn)振動以及平-扭耦聯(lián)作用有效的控制,保證底層柱受力合理。
[Abstract]:With the help of ANSYS software, single pendulum and three pendulum isolation bearings are simulated, and the characteristics of three pendulum isolation bearings are obtained by extracting hysteretic curves. Then, according to the characteristics of asymmetric frame structure, the response of a new type of isolation bearing with triplet friction pendulum to a rare earthquake at 8 degrees is simulated by using numerical simulation. According to the three-fold friction pendulum isolation layer with different upper load and different parameters, the isolation effect is analyzed and compared. The calculation results show that the seismic response of the superstructure can be significantly reduced by using triple friction pendulum isolation. By setting the key parameters of triplet friction pendulum reasonably and adjusting the displacement of isolation layer and superstructure, the horizontal displacement, torsional vibration and horizontal-torsional coupling action of isolation layer can be effectively controlled, and the force of bottom column can be guaranteed to be reasonable.
