为揭示在地震力作用下,水平伸臂加强层的数量和结构布置对框筒结构抗震性能的影响,采用ANSYS有限元分析软件和PKPM-SATWE墙元模型设计软件对某框筒结构进行模态分析和弹性动力时程分析,建立无加强层、设置一道加强层和设置两道加强层的三种模型.通过不同软件对同种模型的对比,以结构的周期、顶点位移值和最大水平位移值的分析为切入点,得出增设一道加强层对提高框筒结构的抗震性能的效果更显著.结果表明:水平伸臂加强层对高层框筒结构抗震性能的提高有重要作用,同时提出了适合于工程实际且更为简便合理的建模方式和分析方法.
In order to reveal the influence of the number and structure of horizontal outrigger reinforcement on the seismic performance of frame-tube structure under the action of seismic force, ANSYS finite element analysis software and PKPM-SATWE wall element model design software were used to simulate the frame structure. Analysis and elastic dynamic time history analysis to establish three kinds of models without strengthening layer, setting a strengthening layer and setting two strengthening layers.Comparing the same model by different software, taking the structure period, vertex displacement and maximum horizontal displacement Value analysis as a starting point, it is found that adding an additional layer is more significant to improve the seismic performance of frame-tube structure. The results show that the horizontal beam-arm reinforcement layer plays an important role in improving the seismic performance of high-rise frame tube structure, Suitable for engineering practice and more convenient and reasonable modeling methods and analysis methods.
