| 摘 要： | 提出了快速矩阵指数法，并将它应用于大型结构的振动分析．以高层建筑为对象，分别计算了10层和30层楼房在外激励作用下的位移响应，在快速矩阵指数法中，每一时间步长是其前一时间步长的2倍．而且能够提供较多的系统信息．实例计算表明，该方法收敛速度快、计算效率高、具有良好的精确度。

| Abstract: | Fast Matrix Exponent Method was introduced and developed for large structure vibration analysis. High construction was taken as numerical examples to illustrate the displacement response of the ten story building and the thirty story building respectively. In the Fast Matrix Exponent Method, the subsequent time interval can be double and more system information can be obtained. The numerical results show that the algorithm converges very fast, and has high efficiency and precision. |
