【摘要】 提出了一种新方法用于求解基础隔震结构。利用复数振型叠加法,这种求解方法能够得出结构动力响应的精确解。所提出的方法兼有解析方法和数值方法优点,又避免了它们所固有的问题。由于有精确解作为基础,方法不但大大减少了计算工作量,而且彻底地避免了许多数值方法所常遇到的精确性、收敛性和稳定性问题。更多还原

【Abstract】 This paper presents a new solution technique for the structure with base isolation devices.The proposed approach can offer an exact solution for dynamic response of base-isolated structure,through using the complex mode superposition method.The proposed method combines merits of analytic method and numerical method and avoids their problems.Based on exact solution,The proposed method not only require much less computational effort,but also thoroughly avoid the problems of accuracy,convergence and stability encountered in many other numerical procedures.更多还原
