【摘要】 针对土与上部结构动力相互作用的问题,采用ANSYS^R软件进行了桩-木-结相互作用线性体系的模态分析,建主了钢筋混凝土剪切型结构的计算模型,研究了桩-土-结相互作用体系的自振特性。结论表明:用ANSYS^R软件可以方便地分析土与结构动力的相互作用,与刚性假定下的结构体系相比,PSSI体系的自振特性发生了变化。更多还原

【Abstract】 In this paper, the problem of soil and super structure in teraction is investigated. By using ANSYS(?) software, a simplified pile-soil-structure interaction (PSSI) model is established for shear -type RC frame structure, the modal analysis is performed and the inherent vibration properties of those structures are investigated. It is convenient to analyse PSSI system with ANSYS, and the inherent vibration properties of PSSI system change compared with the system for rigid assumption.更多还原
