摘要:
对建筑结构地震反应观测台阵在结构抗震设计中的意义进行了简要论述,介绍了大理经济技术开发区管理委员会框架剪力墙大楼内的地震观测台阵测点布设,概述了该台阵在2021年云南漾濞MS6.4地震中获取的强震记录情况,并从峰值加速度和频谱等方面对主震及5.0级以上地震的观测记录进行了分析。结果表明:水平和竖向峰值加速度随着楼层的增加均存在放大现象,震级越大,楼层的水平振动放大效果越明显; 该结构的第一振型和第二振型的自振频率分别为0.48 Hz和1.86 Hz。
Abstract:
In this paper,the significance of the structural seismic response array for the earthquake-resistant design of structure is briefly discussed,and the layout of the measuring points of the structural seismic response array in the building of the Management Committee of Dali Economic and Technological Development Zone is introduced.In addition,the strong-motion records obtained in the MS6.4 Yangbi earthquake event on May 21,2021 is summarized.The peak ground acceleration and the frequency spectrum of the strong motion records of the main shock and the MS≥5.0 after shocks are processed and analysed.The results show that the motions are amplified both in the horizontal and the vertical direction with the ascending of the building’s floor.And as the magnitude increases,the amplification of the motions is more obvious.Meanwhile the natural frequency of the first vibration mode and the second vibration mode is respectively 0.48 Hz and 1.86 Hz.
