A series of comprehensive parametric studies are conducted on a steel-frame structure Finite-Element (FE) model with the Multangular-Pyramid Concave Friction System (MPCFS) installed as isolators. This new introduced MPCFS system has some distinctive features when compared with conventional isolation techniques, such as increased uplift stability, improved self-centering capacity, non-resonance when subjected to near-fault earthquakes, and so on. The FE model of the MPCFS is first established and evaluated by comparison between numerical and theoretical results. The MPCFS FE model is then incorporated in a steel-frame structural model, which is subjected to three chosen earthquakes, to verify its seismic isolation. Further, parametric study with varying controlling parameters, such as isolation foundation, inclination angle, friction coefficient, and earthquake input, is carried out to extract more detailed dynamic response of the MPCFS structure. Finally, limitations of this study are discussed, and conclusions are made. The simulations testify the significant seismic isolation of the MPCFS. This indicates the MPCFS, viewed as the beneficial complementary of the existing well-established and matured isolation techniques, may be a promising tool for seismic isolation of near-fault earthquake prone zones. This verified MPCFS FE model can be incorporated in future FE analysis. The results in this research can also guide future optimal parameter design of the MPCFS.

在钢框架结构有限元（FE）模型上进行了一系列综合参数研究，其中将MMF金字塔隔离凹面摩擦系统（MPCFS）安装为隔离器。与传统的隔离技术相比，这种新引入的MPCFS系统具有一些独特的功能，例如，提高了升力稳定性，提高了自定心能力，在发生近断层地震时不产生共振等。首先建立了MPCFS的有限元模型，并通过数值和理论结果之间的比较对其进行了评估。然后将MPCFS FE模型合并到钢框架结构模型中，该模型经受了三次选定的地震，以验证其地震隔离性。此外，还可以进行具有变化控制参数的参数研究，例如隔离基础，倾斜角度，摩擦系数，进行地震输入，以提取MPCFS结构的更详细的动力响应。最后，讨论了本研究的局限性并得出结论。仿真证明了MPCFS的显着地震隔离。这表明，MPCFS被认为是现有的成熟和成熟的隔离技术的有益补充，可能是用于将近断层地震多发地区进行地震隔离的有前途的工具。该经过验证的MPCFS FE模型可以纳入将来的FE分析中。这项研究的结果也可以指导MPCFS的未来最佳参数设计。仿真证明了MPCFS的显着地震隔离。这表明，MPCFS被认为是现有的成熟和成熟的隔离技术的有益补充，可能是用于将近断层地震多发地区进行地震隔离的有前途的工具。该经过验证的MPCFS FE模型可以纳入将来的FE分析中。这项研究的结果也可以指导MPCFS的未来最佳参数设计。仿真证明了MPCFS的显着地震隔离。这表明，MPCFS被认为是现有的成熟和成熟的隔离技术的有益补充，可能是用于将近断层地震多发地区进行地震隔离的有前途的工具。该经过验证的MPCFS FE模型可以纳入将来的FE分析中。这项研究的结果也可以指导MPCFS的未来最佳参数设计。
