摘要
提出了一种新的地震反应分析法———二维动态有限元分析法。并对它的分析步骤及其重要参数的确定进行了阐述,重点对动态有限元的动态形函数的构造进行了分析。通过工程实例,和一维的地震反应分析法进行了比较,证实了本方法的可行性和合理性。
A new method twodimensional dynamic finite element method(DFE)in analyzing the seismic response of site is put forward firstly. Both the procedure and some important parameters of DFE are discussed. In particular, the constitution of dynamic form function is discussed in detail. Case history using the DFM shows that the results obtained are satisfied. And compared the onedimensional seismic response analysis method, the feasibility and reasonability of DFM are confirmed.
