考虑设备-结构-地基土动力相互作用仿真计算方法
摘要：
本发明涉及一种考虑设备‑结构‑地基土动力相互作用仿真计算方法，步骤如下：整体系统拆分成上部设备‑结构相互作用子结构与下部地基土子结构；将设备‑结构相互作用子结构与地基土子结构隔离，计算得到设备‑结构相互作用子结构作用在基础顶面的剪力Vb和弯矩Mb；建立隔离的地基土子结构在设备‑结构相互作用子结构反力作用下的动力运动方程；分别建立上部设备‑结构相互作用子结构和下部地基土子结构的仿真模型；上部设备‑结构相互作用子结构与下部地基土子结构之间进行交互计算，本发明能够准确的评估考虑设备‑结构‑地基土动力相互作用后对设备或结构抗震性能的影响。
摘要（英）：

The invention relates to a simulation calculation method considering device-structure-foundation soil dynamic interaction. The method comprises the following steps of splitting an integral system into an upper device-structure interaction substructure and a lower foundation soil substructure; isolating the device-structure interaction substructure from the foundation soil substructure, and making a calculation to obtain a shear force Vb and a bending moment Mb of the device-structure interaction substructure acting on a basic top surface; establishing a dynamic motion equation of the isolated foundation soil substructure under the counterforce effect of the device-structure interaction substructure; establishing simulation models of the upper device-structure interaction substructure and the lower foundation soil substructure; and making an interactive calculation between the upper device-structure interaction substructure and the lower foundation soil substructure. According to the method, the influence on the anti-seismic property of a device or a structure after consideration of device-structure-foundation soil dynamic interaction can be accurately assessed.
