用有限单元法分析了双层弹性支承梁的静力响应。
A finite element method is applied to analyze the static response of structure of two-layered beam resting on elastic supports.
同时推导出了结构的静力响应、动态特性、动力响应的灵敏度计算公式；
The formulations of the structural static response, dynamic characteristics and dynamic response based on sensitivity analysis are also deduced in this paper.
然后应用数值传递函数方法对方程求解，就可以得到系统的动力、静力响应。
The equations are solved by the STFM, and the static and dynamic responses of the plane are obtained.
